-.Dt A64L 3
-.Os
-.Sh NAME
-.Nm a64l ,
-.Nm l64a
-.Nd convert between 32-bit integer and radix-64 ASCII string
-.Sh SYNOPSIS
-.In stdlib.h
-.Ft long
-.Fn a64l "const char *s"
-.Ft char *
-.Fn l64a "long l"
-.Sh DESCRIPTION
-The
-.Fn a64l
-and
-.Fn l64a
-functions are used to maintain numbers stored in radix-64
-.Tn ASCII
-characters.
-This is a notation by which 32-bit integers
-can be represented by up to six characters; each character represents a
-.Dq digit
-in a radix-64 notation.
-.Pp
-The characters used to represent digits are
-.Ql \&.
-for 0,
-.Ql /
-for 1,
-.Ql 0
-through
-.Ql 9
-for 2-11,
-.Ql A
-through
-.Ql Z
-for 12-37, and
-.Ql a
-through
-.Ql z
-for 38-63.
-.Pp
-The
-.Fn a64l
-function takes a pointer to a NUL-terminated radix-64 representation
-and returns a corresponding 32-bit value.
-If the string pointed to by
-.Fa s
-contains more than six characters,
-.Fn a64l
-will use the first six.
-.Fn a64l
-scans the character string from left to right, decoding
-each character as a 6-bit radix-64 number.
-If a long integer is
-larger than 32 bits, the return value will be sign-extended.
-.Pp
-.Fn l64a
-takes a long integer argument
-.Fa l
-and returns a pointer to the corresponding radix-64 representation.
-.Sh RETURN VALUES
-On success,
-.Fn a64l
-returns a 32-bit representation of
-.Fa s .
-If
-.Fa s
-is a null pointer or if it contains digits other than those described above,
-.Fn a64l
-returns \-1 and sets the global variable
-.Va errno
-to
-.Er EINVAL .
-.Pp
-On success,
-.Fn l64a
-returns a pointer to a string containing the radix-64 representation of
-.Fa l .
-If
-.Fa l
-is 0,
-.Fn l64a
-returns a pointer to the empty string.
-If
-.Fa l
-is negative,
-.Fn l64a
-returns a null pointer and sets the global variable
-.Va errno
-to
-.Er EINVAL .
-.Sh STANDARDS
-The
-.Fn a64l
-and
-.Fn l64a
-functions conform to
-.St -xpg4.2 .
-.Sh CAVEATS
-The value returned by
-.Fn l64a
-is a pointer into a static buffer, the contents of which
-will be overwritten by subsequent calls.
-.Pp
-The value returned by
-.Fn a64l
-may be incorrect if the value is too large; for that reason, only strings
-that resulted from a call to
-.Fn l64a
-should be used to call
-.Fn a64l .
-.Pp
-If a long integer is larger than 32 bits, only the low-order
-32 bits are used.

-.Sh DESCRIPTION
-The

-is being caught and the signal handler does not return.
-.Pp
-Some implementations may flush output streams before terminating.
-This implementation does not.

-.Sh HISTORY
-The
-.Fn abort
-function first appeared in
-.At v5 .
-.Pp
-Historically, previous standards required
-.Fn abort
-to flush and close output streams, but this conflicted with the requirement
-that
-.Fn abort
-be async signal safe.
-As a result, the flushing requirement was dropped.

-The

-This temporary space is automatically freed on return.
-.Sh RETURN VALUES
-The

-.Sh CAVEATS
-The

-The allocation made may exceed the bounds of the stack, or even go
-further into other objects in memory, and

-cannot determine such an error.
-Avoid
-.Fn alloca
-with large unbounded allocations.

-.Os
-.Sh NAME
-.Nm atexit
-.Nd register a function to be called on exit
-.Sh SYNOPSIS
-.In stdlib.h
-.Ft int
-.Fn atexit "void (*function)(void)"
-.Sh DESCRIPTION
-The
-.Fn atexit
-function registers the given
-.Fa function
-to be called at program exit, whether via
-.Xr exit 3
-or via return from the program's
-.Fn main .
-Functions so registered are called in reverse order;
-no arguments are passed.
-At least 32 functions can always be registered,
-and more are allowed as long as sufficient memory can be allocated.
-.Pp
-If a shared object is unloaded from process memory using
-.Xr dlclose 3 ,
-then any functions registered by calling
-.Fn atexit
-from that shared object will be called in reverse order and unregistered.
-Note that it is the source of the call to
-.Fn atexit
-that matters, not the source of the function that was registered.
-.Pp
-.Fn atexit
-is very difficult to use correctly without creating
-.Xr exit 3 Ns -time
-races.
-Unless absolutely necessary, please avoid using it.
-.Sh RETURN VALUES
-The
-.Nm
-function returns the value 0 if successful; otherwise a non-zero
-value is returned and the global variable
-.Va errno
-is set to indicate the error.
-.Sh ERRORS
-.Bl -tag -width Er
-.It Bq Er ENOMEM
-No memory was available to add the function to the list.
-The existing list of functions is unmodified.
-.El
-.Sh SEE ALSO
-.Xr dlclose 3 ,
-.Xr exit 3
-.Sh STANDARDS
-The
-.Fn atexit
-function conforms to
-.St -ansiC .
-.Pp
-Setting
-.Va errno
-on error and the behavior when a shared object is unloaded
-are extensions to that standard.

-.Pp
-The contents of the array should be in ascending sorted order according

-.Fa compar .
-The
-.Fa compar
-routine is expected to have two arguments which point to the

-object and to an array member, in that order, and should return an integer
-less than, equal to, or greater than zero if the
-.Fa key
-object is found, respectively, to be less than, to match, or be
-greater than the array member.
-.Sh RETURN VALUES
-The

-pointer if no match is found.
-If two members compare as equal, which member is matched is unspecified.

-.Dt ECVT 3
-.Os
-.Sh NAME
-.Nm ecvt ,
-.Nm fcvt ,
-.Nm gcvt
-.Nd convert double to ASCII string
-.Sh SYNOPSIS
-.In stdlib.h
-.Ft char *
-.Fn ecvt "double value" "int ndigit" "int *decpt" "int *sign"
-.Ft char *
-.Fn fcvt "double value" "int ndigit" "int *decpt" "int *sign"
-.Ft char *
-.Fn gcvt "double value" "int ndigit" "char *buf"
-.Sh DESCRIPTION
-.Bf -symbolic
-These functions are provided for compatibility with legacy code.
-New code should use the
-.Xr snprintf 3
-function for improved safety and portability.
-.Ef
-.Pp
-The
-.Fn ecvt ,
-.Fn fcvt
-and
-.Fn gcvt
-functions convert the double precision floating-point number
-.Fa value
-to a NUL-terminated
-.Tn ASCII
-string.
-.Pp
-The
-.Fn ecvt
-function converts
-.Fa value
-to a NUL-terminated string of exactly
-.Fa ndigit
-digits and returns a pointer to that string.
-The result is padded with zeroes from left to right as needed.
-There are no leading zeroes unless
-.Fa value
-itself is 0.
-The least significant digit is rounded in an implementation-dependent manner.
-The position of the decimal point relative to the beginning of the string
-is stored in
-.Fa decpt .
-A negative value indicates that the decimal point is located
-to the left of the returned digits (this occurs when there is no
-whole number component to
-.Fa value ) .
-If
-.Fa value
-is zero, it is unspecified whether the integer pointed to by
-.Fa decpt
-will be 0 or 1.
-The decimal point itself is not included in the returned string.
-If the sign of the result is negative, the integer pointed to by
-.Fa sign
-is non-zero; otherwise, it is 0.
-.Pp
-If the converted value is out of range or is not representable,
-the contents of the returned string are unspecified.
-.Pp
-The
-.Fn fcvt
-function is identical to
-.Fn ecvt
-with the exception that
-.Fa ndigit
-specifies the number of digits after the decimal point (zero-padded as
-needed).
-.Pp
-The
-.Fn gcvt
-function converts
-.Fa value
-to a NUL-terminated string similar to the %g
-.Xr printf 3
-format specifier and stores the result in
-.Fa buf .
-It produces
-.Fa ndigit
-significant digits similar to the %f
-.Xr printf 3
-format specifier where possible.
-If
-.Fa ndigit
-does allow sufficient precision, the result is stored in
-exponential notation similar to the %e
-.Xr printf 3
-format specifier.
-If
-.Fa value
-is less than zero,
-.Fa buf
-will be prefixed with a minus sign.
-A decimal point is included in the returned string if
-.Fa value
-is not a whole number.
-Unlike the
-.Fn ecvt
-and
-.Fn fcvt
-functions,
-.Fa buf
-is not zero-padded.
-.Sh RETURN VALUES
-The
-.Fn ecvt ,
-.Fn fcvt
-and
-.Fn gcvt
-functions return a NUL-terminated string representation of
-.Fa value .
-.Sh SEE ALSO
-.Xr printf 3 ,
-.Xr strtod 3
-.Sh STANDARDS
-The
-.Fn ecvt ,
-.Fn fcvt
-and
-.Fn gcvt
-functions conform to
-.St -p1003.1-2001 ;
-as of
-.St -p1003.1-2008
-they are no longer a part of the standard.
-.Sh CAVEATS
-The
-.Fn ecvt
-and
-.Fn fcvt
-functions return a pointer to internal storage space that will be
-overwritten by subsequent calls to either function.
-.Pp
-The maximum possible precision of the return value is limited by the
-precision of a double and may not be the same on all architectures.
-.Pp
-The
-.Xr snprintf 3
-function is preferred over these functions for new code.

-.Os
-.Sh NAME
-.Nm getenv ,
-.Nm putenv ,
-.Nm setenv ,
-.Nm unsetenv
-.Nd environment variable functions
-.Sh SYNOPSIS
-.In stdlib.h
-.Ft char *
-.Fn getenv "const char *name"
-.Ft int
-.Fn setenv "const char *name" "const char *value" "int overwrite"
-.Ft int
-.Fn putenv "char *string"
-.Ft int
-.Fn unsetenv "const char *name"
-.Sh DESCRIPTION
-These functions set, unset, and fetch environment variables from the host
-.Em environment list .
-.Pp
-The
-.Fn getenv
-function obtains the current value of the environment variable
-.Fa name .
-If the variable
-.Fa name
-is not in the current environment, a null pointer is returned.
-.Pp
-The
-.Fn setenv
-function inserts or resets the environment variable
-.Fa name
-in the current environment list.
-If the variable
-.Fa name
-does not exist in the list, it is inserted with the given
-.Fa value .
-If the variable does exist, the argument
-.Fa overwrite
-is tested; if
-.Fa overwrite
-is zero, the variable is not reset, otherwise it is reset to the given
-.Fa value .
-.Pp
-The
-.Fn putenv
-function takes an argument of the form
-.Ar name Ns = Ns Ar value .
-The memory pointed to by
-.Ar string
-becomes part of the environment and must not be deallocated by the caller.
-If the variable already exists, it will be overwritten.
-A common source of bugs is to pass a
-.Ar string
-argument that is a locally scoped string buffer.
-This will result in corruption of the environment after leaving
-the scope in which the variable is defined.
-For this reason, the
-.Fn setenv
-function is preferred over
-.Fn putenv .
-.Pp
-The
-.Fn unsetenv
-function deletes all instances of the variable name pointed to by
-.Fa name
-from the list.
-.Sh RETURN VALUES
-.Rv -std putenv setenv unsetenv
-.Pp
-The
-.Fn getenv
-function returns a pointer to the requested value, or
-.Dv NULL
-if it could not be found.
-If
-.Fn getenv
-is successful, the string returned should be considered read-only.
-.Sh ERRORS
-.Bl -tag -width Er
-.It Bq Er EINVAL
-The
-.Fn setenv
-or
-.Fn unsetenv
-function was passed an empty
-.Ar name
-or a NULL pointer, or was passed a
-.Ar name
-containing an
-.Sq =
-character.
-.Pp
-The
-.Fn putenv
-function was passed a
-.Ar string
-that did not contain an
-.Sq =
-character.
-.It Bq Er ENOMEM
-The
-.Fn setenv
-or
-.Fn putenv
-function failed because it was unable to allocate memory for the environment.
-.El
-.Sh SEE ALSO
-.Xr csh 1 ,
-.Xr sh 1 ,
-.Xr execve 2 ,
-.Xr issetugid 2 ,
-.Xr environ 7
-.Sh STANDARDS
-The
-.Fn getenv
-function conforms to
-.St -ansiC .
-The
-.Fn putenv ,
-.Fn setenv ,
-and
-.Fn unsetenv
-functions conform to
-.St -p1003.1-2008 .
-.Sh HISTORY
-The function
-.Fn getenv
-appeared in
-.At v7
-and
-.Bx 3 .
-The functions
-.Fn setenv
-and
-.Fn unsetenv
-appeared in
-.Bx 4.3 Tahoe .
-The
-.Fn putenv
-function appeared in
-.Bx 4.3 Reno .
-.Sh CAVEATS
-Library code must be careful about using
-.Fn getenv
-to read untrusted environment variables in setuid programs.
-The
-.Fn issetugid
-function is provided for this purpose.

-.Fn getopt "int argc" "char * const *argv" "const char *optstring"
-.Sh DESCRIPTION
-The
-.Fn getopt
-function incrementally parses a command line argument list
-.Fa argv
-and returns the next
-.Em known
-option character.
-An option character is
-.Em known
-if it has been specified in the string of accepted option characters,
-.Fa optstring .
-.Pp
-The option string
-.Fa optstring
-may contain the following elements: individual characters,
-characters followed by a colon, and characters followed by two colons.
-A character followed by a single colon indicates that an argument
-is to follow the option on the command line.
-Two colons indicates that the argument is optional \- this is an
-extension not covered by POSIX.
-For example, an option string
-.Qq x
-recognizes an option
-.Fl x ,
-and an option string
-.Qq Li x:
-recognizes an option and argument
-.Fl x Ar argument .
-It does not matter to
-.Fn getopt
-if a following argument has leading whitespace; except in the case where
-the argument is optional, denoted with two colons, no leading whitespace
-is permitted.
-.Pp
-On return from
-.Fn getopt ,
-.Va optarg
-points to an option argument, if it is anticipated,
-and the variable
-.Va optind
-contains the index to the next
-.Fa argv
-argument for a subsequent call
-to
-.Fn getopt .
-.Pp
-The variables
-.Va opterr
-and
-.Va optind
-are both initialized to 1.
-The
-.Va optind
-variable may be set to another value larger than 0 before a set of calls to
-.Fn getopt
-in order to skip over more or less
-.Fa argv
-entries.
-An
-.Va optind
-value of 0 is reserved for compatibility with GNU
-.Fn getopt .
-.Pp
-In order to use
-.Fn getopt
-to evaluate multiple sets of arguments, or to evaluate a single set of
-arguments multiple times,
-the variable
-.Va optreset
-must be set to 1 before the second and each additional set of calls to
-.Fn getopt ,
-and the variable
-.Va optind
-must be reinitialized.
-.Pp
-The
-.Fn getopt
-function returns \-1 when the argument list is exhausted.
-The interpretation of options in the argument list may be cancelled
-by the option
-.Ql --
-(double dash) which causes
-.Fn getopt
-to signal the end of argument processing and return \-1.
-When all options have been processed (i.e., up to the first non-option
-argument),
-.Fn getopt
-returns \-1.
-.Sh RETURN VALUES
-The
-.Fn getopt
-function returns the next known option character in
-.Fa optstring .
-If
-.Fn getopt
-encounters a character not found in
-.Fa optstring
-or if it detects a missing option argument,
-it returns
-.Sq \&?
-(question mark).
-If
-.Fa optstring
-has a leading
-.Sq \&:
-then a missing option argument causes
-.Sq \&:
-to be returned instead of
-.Sq \&? .
-In either case, the variable
-.Va optopt
-is set to the character that caused the error.
-The
-.Fn getopt
-function returns \-1 when the argument list is exhausted.
-.Sh EXAMPLES
-The following code accepts the options
-.Fl b
-and
-.Fl f Ar argument
-and adjusts
-.Va argc
-and
-.Va argv
-after option argument processing has completed.
-.Bd -literal -offset indent
-int bflag, ch, fd;
-
-bflag = 0;
-while ((ch = getopt(argc, argv, "bf:")) != -1) {
-        switch (ch) {
-        case 'b':
-                bflag = 1;
-                break;
-        case 'f':
-                if ((fd = open(optarg, O_RDONLY, 0)) == -1)
-                        err(1, "%s", optarg);
-                break;
-        default:
-                usage();
-        }

-argc -= optind;
-argv += optind;
-.Ed
-.Sh DIAGNOSTICS
-If the
-.Fn getopt
-function encounters a character not found in the string
-.Fa optstring
-or detects
-a missing option argument, it writes an error message to
-.Em stderr
-and returns
-.Ql \&? .
-Setting
-.Va opterr
-to a zero will disable these error messages.
-If
-.Fa optstring
-has a leading
-.Ql \&:
-then a missing option argument causes a
-.Ql \&:
-to be returned in addition to suppressing any error messages.
-.Pp
-Option arguments are allowed to begin with
-.Ql - ;
-this is reasonable but reduces the amount of error checking possible.

-.Sh STANDARDS
-The
-.Fn getopt
-function implements a superset of the functionality specified by
-.St -p1003.1 .
-.Pp
-The following extensions are supported:
-.Bl -bullet
-.It
-The
-.Va optreset
-variable was added to make it possible to call the
-.Fn getopt
-function multiple times.
-.It
-If the
-.Va optind
-variable is set to 0,
-.Fn getopt
-will behave as if the
-.Va optreset
-variable has been set.
-This is for compatibility with
-.Tn GNU
-.Fn getopt .
-New code should use
-.Va optreset
-instead.
-.It
-If the first character of
-.Fa optstring
-is a plus sign
-.Pq Ql + ,
-it will be ignored.
-This is for compatibility with
-.Tn GNU
-.Fn getopt .
-.It
-If the first character of
-.Fa optstring
-is a dash
-.Pq Ql - ,
-non-options will be returned as arguments to the option character
-.Ql \e1 .
-This is for compatibility with
-.Tn GNU
-.Fn getopt .
-.It
-A single dash
-.Pq Ql -
-may be specified as a character in
-.Fa optstring ,
-however it should
-.Em never
-have an argument associated with it.
-This allows
-.Fn getopt
-to be used with programs that expect
-.Ql -
-as an option flag.
-This practice is wrong, and should not be used in any current development.
-It is provided for backward compatibility
-.Em only .
-Care should be taken not to use
-.Ql -
-as the first character in
-.Fa optstring
-to avoid a semantic conflict with
-.Tn GNU
-.Fn getopt
-semantics (see above).
-By default, a single dash causes
-.Fn getopt
-to return \-1.
-.El
-.Pp
-Historic
-.Bx
-versions of
-.Fn getopt
-set
-.Fa optopt
-to the last option character processed.
-However, this conflicts with
-.St -p1003.1
-which stipulates that
-.Fa optopt
-be set to the last character that caused an error.
-.Sh HISTORY
-The
-.Fn getopt
-function appeared in
-.Bx 4.3 .
-.Sh BUGS
-The
-.Fn getopt
-function was once specified to return
-.Dv EOF
-instead of \-1.
-This was changed by
-.St -p1003.2-92
-to decouple
-.Fn getopt
-from
-.In stdio.h .
-.Pp
-It is possible to handle digits as option letters.
-This allows
-.Fn getopt
-to be used with programs that expect a number
-.Pq Dq Li \-3
-as an option.
-This practice is wrong, and should not be used in any current development.
-It is provided for backward compatibility
-.Em only .
-The following code fragment works in most cases and can handle mixed
-number and letter arguments.
-.Bd -literal -offset indent
-int aflag = 0, bflag = 0, ch, lastch = '\e0';
-int length = -1, newarg = 1, prevoptind = 1;
-
-while ((ch = getopt(argc, argv, "0123456789ab")) != -1) {
-        switch (ch) {
-        case '0': case '1': case '2': case '3': case '4':
-        case '5': case '6': case '7': case '8': case '9':
-                if (newarg || !isdigit(lastch))
-                        length = 0;
-                else if (length > INT_MAX / 10)
-                        usage();
-                length = (length * 10) + (ch - '0');

-.Os
-.Sh NAME
-.Nm getopt_long ,
-.Nm getopt_long_only
-.Nd get long options from command line argument list
-.Sh SYNOPSIS
-.In getopt.h
-.Vt extern char *optarg;
-.Vt extern int optind;
-.Vt extern int optopt;
-.Vt extern int opterr;
-.Vt extern int optreset;
-.Ft int
-.Fn getopt_long "int argc" "char * const *argv" "const char *optstring" "const struct option *longopts" "int *longindex"
-.Ft int
-.Fn getopt_long_only "int argc" "char * const *argv" "const char *optstring" "const struct option *longopts" "int *longindex"
-.Sh DESCRIPTION
-The
-.Fn getopt_long
-function is similar to
-.Xr getopt 3
-but it accepts options in two forms: words and characters.
-The
-.Fn getopt_long
-function provides a superset of the functionality of
-.Xr getopt 3 .
-.Fn getopt_long
-can be used in two ways.
-In the first way, every long option understood by the program has a
-corresponding short option, and the option structure is only used to
-translate from long options to short options.
-When used in this fashion,
-.Fn getopt_long
-behaves identically to
-.Xr getopt 3 .
-This is a good way to add long option processing to an existing program
-with the minimum of rewriting.
-.Pp
-In the second mechanism, a long option sets a flag in the
-.Fa option
-structure passed, or will store a pointer to the command line argument
-in the
-.Fa option
-structure passed to it for options that take arguments.
-Additionally, the long option's argument may be specified as a single
-argument with an equal sign, e.g.
-.Bd -literal -offset indent
-$ myprogram --myoption=somevalue
-.Ed
-.Pp
-When a long option is processed, the call to
-.Fn getopt_long
-will return 0.
-For this reason, long option processing without
-shortcuts is not backwards compatible with
-.Xr getopt 3 .
-.Pp
-It is possible to combine these methods, providing for long options
-processing with short option equivalents for some options.
-Less frequently used options would be processed as long options only.
-.Pp
-Abbreviated long option names are accepted when
-.Fn getopt_long
-processes long options if the abbreviation is unique.
-An exact match is always preferred for a defined long option.
-.Pp
-By default,
-.Fn getopt_long
-permutes
-.Ar argv
-such that all option arguments are evaluated before any non-options arguments.
-If the first character of
-.Fa optstring
-is a plus sign
-.Pq Ql +
-or if the environment variable
-.Ev POSIXLY_CORRECT
-is set, then
-.Ar argv
-is processed in order and option processing stops as soon as the first
-non-option argument is encountered.
-.Pp
-The
-.Fn getopt_long
-call requires an array to be initialized describing the long
-options.
-Each element of the array is a structure:
-.Bd -literal -offset indent
-struct option {
-        char *name;
-        int has_arg;
-        int *flag;
-        int val;
-};
-.Ed
-.Pp
-The
-.Fa name
-field should contain the option name without the leading double dash.
-.Pp
-The
-.Fa has_arg
-field should be one of:
-.Pp
-.Bl -tag -width "optional_argument" -compact -offset indent
-.It Dv no_argument
-no argument to the option is expected.
-.It Dv required_argument
-an argument to the option is required.
-.It Dv optional_argument
-an argument to the option may be presented.
-.El
-.Pp
-If
-.Fa flag
-is not
-.Dv NULL ,
-then the integer pointed to by it will be set to the value in the
-.Fa val
-field.
-If the
-.Fa flag
-field is
-.Dv NULL ,
-then the
-.Fa val
-field will be returned.
-Setting
-.Fa flag
-to
-.Dv NULL
-and setting
-.Fa val
-to the corresponding short option will make this function act just
-like
-.Xr getopt 3 .
-.Pp
-If the
-.Fa longindex
-field is not
-.Dv NULL ,
-then the integer pointed to by it will be set to the index of the long
-option relative to
-.Fa longopts .
-.Pp
-The last element of the
-.Fa longopts
-array has to be filled with zeroes.
-.Pp
-The
-.Fn getopt_long_only
-function behaves identically to
-.Fn getopt_long
-with the exception that long options may start with
-.Sq -
-in addition to
-.Sq -- .
-If an option starting with
-.Sq -
-does not match a long option but does match a single-character option,
-the single-character option is returned.
-.Sh RETURN VALUES
-If the
-.Fa flag
-field in
-.Li struct option
-is
-.Dv NULL ,
-.Fn getopt_long
-and
-.Fn getopt_long_only
-return the value specified in the
-.Fa val
-field, which is usually just the corresponding short option.
-If
-.Fa flag
-is not
-.Dv NULL ,
-these functions return 0 and store
-.Fa val
-in the location pointed to by
-.Fa flag .
-These functions return
-.Sq \&:
-if there was a missing option argument,
-.Sq \&?
-if the user specified an unknown or ambiguous option, and
-\-1 when the argument list has been exhausted.
-.Sh IMPLEMENTATION DIFFERENCES
-This section describes differences to the GNU implementation
-found in glibc-2.1.3:
-.Bl -bullet
-.It
-handling of
-.Ql -
-within the option string (not the first character):
-.Bl -tag -width "OpenBSD"
-.It GNU
-treats a
-.Ql -
-on the command line as a non-argument.
-.It OpenBSD
-a
-.Ql -
-within the option string matches a
-.Ql -
-(single dash) on the command line.
-This functionality is provided for backward compatibility with
-programs, such as
-.Xr su 1 ,
-that use
-.Ql -
-as an option flag.
-This practice is wrong, and should not be used in any current development.
-.El
-.It
-handling of
-.Ql ::
-in the option string in the presence of
-.Ev POSIXLY_CORRECT :
-.Bl -tag -width "OpenBSD"
-.It Both
-GNU and
-.Ox
-ignore
-.Ev POSIXLY_CORRECT
-here and take
-.Ql ::
-to mean the preceding option takes an optional argument.
-.El
-.It
-return value in case of missing argument if first character
-(after
-.Ql +
-or
-.Ql - )
-in the option string is not
-.Ql \&: :
-.Bl -tag -width "OpenBSD"
-.It GNU
-returns
-.Ql \&?
-.It OpenBSD
-returns
-.Ql \&:
-(since
-.Ox Ns 's
-.Xr getopt 3
-does).
-.El
-.It
-handling of
-.Ql --a
-in
-.Xr getopt 3 :
-.Bl -tag -width "OpenBSD"
-.It GNU
-parses this as option
-.Ql - ,
-option
-.Ql a .
-.It OpenBSD
-parses this as
-.Ql -- ,
-and returns \-1 (ignoring the
-.Ql a )
-(because the original
-.Fn getopt
-did.)
-.El
-.It
-setting of
-.Va optopt
-for long options with
-.Va flag
-.No non- Ns Dv NULL :
-.Bl -tag -width "OpenBSD"
-.It GNU
-sets
-.Va optopt
-to
-.Va val .
-.It OpenBSD
-sets
-.Va optopt
-to 0 (since
-.Va val
-would never be returned).
-.El
-.It
-handling of
-.Ql -W
-with
-.Ql W;
-in the option string in
-.Xr getopt 3
-(not
-.Fn getopt_long ) :
-.Bl -tag -width "OpenBSD"
-.It GNU
-causes a segmentation fault.
-.It OpenBSD
-no special handling is done;
-.Ql W;
-is interpreted as two separate options, neither of which take an argument.
-.El
-.It
-setting of
-.Va optarg
-for long options without an argument that are invoked via
-.Ql -W
-(with
-.Ql W;
-in the option string):
-.Bl -tag -width "OpenBSD"
-.It GNU
-sets
-.Va optarg
-to the option name (the argument of
-.Ql -W ) .
-.It OpenBSD
-sets
-.Va optarg
-to
-.Dv NULL
-(the argument of the long option).
-.El
-.It
-handling of
-.Ql -W
-with an argument that is not (a prefix to) a known long option
-(with
-.Ql W;
-in the option string):
-.Bl -tag -width "OpenBSD"
-.It GNU
-returns
-.Ql -W
-with
-.Va optarg
-set to the unknown option.
-.It OpenBSD
-treats this as an error (unknown option) and returns
-.Ql \&?
-with
-.Va optopt
-set to 0 and
-.Va optarg
-set to
-.Dv NULL
-(as GNU's man page documents).
-.El
-.It
-The error messages are different.
-.It
-.Ox
-does not permute the argument vector at the same points in
-the calling sequence as GNU does.
-The aspects normally used by the caller
-(ordering after \-1 is returned, value of
-.Va optind
-relative to current positions) are the same, though.
-(We do fewer variable swaps.)
-.El
-.Sh ENVIRONMENT
-.Bl -tag -width Ev
-.It Ev POSIXLY_CORRECT
-If set, option processing stops when the first non-option is found and
-a leading

-.Os
-.Sh NAME
-.Nm getsubopt
-.Nd get sub options from an argument
-.Sh SYNOPSIS
-.In stdlib.h
-.Vt extern char *suboptarg;
-.Ft int
-.Fn getsubopt "char **optionp" "char * const *tokens" "char **valuep"
-.Sh DESCRIPTION
-The
-.Fn getsubopt
-function parses a string containing tokens delimited by one or more
-tab, space, or comma
-.Pq Ql \&,
-characters.
-It is intended for use in parsing groups of option arguments provided
-as part of a utility command line.
-.Pp
-The argument
-.Fa optionp
-is a pointer to a pointer to the string.
-The argument
-.Fa tokens
-is a pointer to a null-terminated array of pointers to strings.
-.Pp
-The
-.Fn getsubopt
-function returns the zero-based offset of the pointer in the
-.Fa tokens
-array referencing a string which matches the first token
-in the string, or \-1 if the string contains no tokens or
-.Fa tokens
-does not contain a matching string.
-.Pp
-If the token is of the form
-.Ar name Ns = Ns Ar value ,
-the location referenced by
-.Fa valuep
-will be set to point to the start of the
-.Dq value
-portion of the token.
-.Pp
-On return from
-.Fn getsubopt ,
-.Fa optionp
-will be set to point to the start of the next token in the string,
-or the NUL at the end of the string if no more tokens are present.
-The external variable
-.Fa suboptarg
-will be set to point to the start of the current token, or
-.Dv NULL
-if no tokens were present.
-The argument
-.Fa valuep
-will be set to point to the value portion of the token, or
-.Dv NULL
-if no value portion was present.

-.Dt HCREATE 3
-.Os
-.Sh NAME
-.Nm hcreate ,
-.Nm hdestroy ,
-.Nm hsearch
-.Nd manage hash search table
-.Sh SYNOPSIS
-.In search.h
-.Ft int
-.Fn hcreate "size_t nel"
-.Ft void
-.Fn hdestroy "void"
-.Ft ENTRY *
-.Fn hsearch "ENTRY item" "ACTION action"
-.Sh DESCRIPTION
-The
-.Fn hcreate ,
-.Fn hdestroy ,
-and
-.Fn hsearch
-functions manage hash search tables.
-.Pp
-The
-.Fn hcreate
-function allocates and initializes the table.
-The
-.Fa nel
-argument specifies an estimate of the maximum number of entries to be held
-by the table.
-Unless further memory allocation fails, supplying an insufficient
-.Fa nel
-value will not result in functional harm, although a performance degradation
-may occur.
-Initialization using the
-.Fn hcreate
-function is mandatory prior to any access operations using
-.Fn hsearch .
-.Pp
-The
-.Fn hdestroy
-function destroys a table previously created using
-.Fn hcreate .
-After a call to
-.Fn hdestroy ,
-the data can no longer be accessed.
-.Pp
-The
-.Fn hsearch
-function is used to search the hash table.
-It returns a pointer into the
-hash table indicating the address of an item.
-The
-.Fa item
-argument is of type
-.Vt ENTRY ,
-defined in the
-.In search.h
-header.
-This is a structure type that contains two pointers:
-.Pp
-.Bl -tag -compact -offset indent -width "void *data "
-.It Fa char *key
-comparison key
-.It Fa void *data
-pointer to data associated with
-.Fa key
-.El
-.Pp
-The key comparison function used by
-.Fn hsearch
-is
-.Xr strcmp 3 .
-.Pp
-The
-.Fa action
-argument is of type
-.Vt ACTION ,
-an enumeration type which defines the following values:
-.Bl -tag -offset indent -width ENTERXX
-.It Dv ENTER
-Insert
-.Fa item
-into the hash table.
-If an existing item with the same key is found, it is not replaced.
-Note that the
-.Fa key
-and
-.Fa data
-elements of
-.Fa item
-are used directly by the new table entry.
-The storage for the
-key must not be modified during the lifetime of the hash table.
-.It Dv FIND
-Search the hash table without inserting
-.Fa item .
-.El
-.Pp
-Note that the comparison
-.Fa key
-must be allocated using
-.Xr malloc 3
-or
-.Xr calloc 3
-if action is
-.Dv ENTER
-and
-.Fn hdestroy
-will be called.
-This is because
-.Fn hdestroy
-will call
-.Xr free 3
-for each comparison
-.Fa key
-(but not
-.Fa data ) .
-Typically the comparison
-.Fa key
-is allocated by using
-.Xr strdup 3 .
-.Sh RETURN VALUES
-If successful, the
-.Fn hcreate
-function returns a non-zero value.
-Otherwise, a value of 0 is returned and
-.Va errno
-is set to indicate the error.
-.Pp
-If successful, the
-.Fn hsearch
-function returns a pointer to a hash table entry matching
-the provided key.
-If the action is
-.Dv FIND
-and the item was not found, or if the action is
-.Dv ENTER
-and the insertion failed,
-.Dv NULL
-is returned and
-.Va errno
-is set to indicate the error.
-If the action is
-.Dv ENTER
-and an entry already existed in the table matching the given
-key, the existing entry is returned and is not replaced.
-.Sh ERRORS
-The
-.Fn hcreate
-and
-.Fn hsearch
-functions will fail if:
-.Bl -tag -width Er
-.It Bq Er ENOMEM

-.Dt INSQUE 3
-.Os
-.Sh NAME
-.Nm insque ,
-.Nm remque
-.Nd legacy doubly linked lists
-.Sh SYNOPSIS
-.In search.h
-.Ft void
-.Fn insque "void *elem" "void *pred"
-.Ft void
-.Fn remque "void *elem"
-.Sh DESCRIPTION
-.Bf -symbolic
-These interfaces have been superseded by the
-.Xr queue 3
-macros and are provided for compatibility with legacy code.
-.Ef
-.Pp
-.Fn insque
-and
-.Fn remque
-manipulate a legacy variety of intrusive doubly linked lists.
-A list can be either circular or linear.
-Each element in the list must be of the following form:
-.Bd -literal -offset indent
-struct qelem {
-        struct qelem   *q_forw;
-        struct qelem   *q_back;
-        char            q_data[];
-};
-.Ed
-.Pp
-The first two members of the struct must be pointers of the
-same type that point to the next and previous elements in
-the list, respectively.
-Any subsequent data in the struct is application-dependent.
-.Pp
-The
-.Fn insque
-function inserts
-.Fa elem
-into a list immediately after
-.Fa pred .
-.Pp
-The
-.Fn remque
-function removes
-.Fa elem
-from the list.
-.Pp
-These functions are not atomic.
-.Sh SEE ALSO
-.Xr queue 3
-.Sh STANDARDS
-The
-.Fn insque
-and
-.Fn remque
-functions conform to the X/Open System Interfaces option of the
-.St -p1003.1-2008
-specification.
-.Sh HISTORY
-The
-.Fn insque
-and
-.Fn remque
-functions are derived from the
-.Li insque
-and
-.Li remque
-instructions on the VAX.
-They first appeared in
-.Bx 4.2 .

-.Sh NAME
-.Nm lsearch ,
-.Nm lfind
-.Nd linear searching routines
-.Sh SYNOPSIS
-.In search.h
-.Ft void *
-.Fn lsearch "const void *key" "void *base" "size_t *nelp" \
-    "size_t width" "int (*compar)(const void *, const void *)"
-.Ft void *
-.Fn lfind "const void *key" "const void *base" "size_t *nelp" \
-    "size_t width" "int (*compar)(const void *, const void *)"
-.Sh DESCRIPTION
-The functions
-.Fn lsearch
-and
-.Fn lfind
-provide basic linear searching functionality.
-.Pp
-.Fa base
-is the pointer to the beginning of an array.
-The argument
-.Fa nelp
-is the current number of elements in the array, where each element
-is
-.Fa width
-bytes long.
-The
-.Fa compar
-function
-is a comparison routine which is used to compare two elements.
-It takes two arguments which point to the
-.Fa key
-object and to an array member, in that order, and must return an integer
-less than, equivalent to, or greater than zero if the
-.Fa key
-object is considered, respectively, to be less than, equal to, or greater
-than the array member.
-.Pp
-The
-.Fn lsearch
-and
-.Fn lfind
-functions
-return a pointer into the array referenced by
-.Fa base
-where
-.Fa key
-is located.
-If
-.Fa key
-does not exist,
-.Fn lfind
-will return a null pointer and
-.Fn lsearch
-will add it to the array.
-When an element is added to the array by
-.Fn lsearch ,
-the location referenced by the argument
-.Fa nelp
-is incremented by one.
-.Sh SEE ALSO
-.Xr bsearch 3 ,
-.Xr dbopen 3
-.Sh STANDARDS
-The
-.Fn lsearch
-and
-.Fn lfind
-functions conform to the X/Open System Interfaces option of the
-.St -p1003.1-2008
-specification.

-.Sh DESCRIPTION
-The standard functions
-.Fn malloc ,
-.Fn calloc ,
-and
-.Fn realloc
-allocate
-.Em objects ,
-regions of memory to store values.
-The
-.Fn malloc
-function allocates uninitialized space for an object of
-the specified
-.Fa size .
-.Fn malloc
-maintains multiple lists of free objects according to size, allocating
-from the appropriate list or requesting memory from the kernel.
-The allocated space is suitably aligned (after possible pointer coercion) for
-storage of any type of object.
-.Pp
-The
-.Fn calloc
-function allocates space for an array of
-.Fa nmemb
-objects, each of the specified
-.Fa size .
-The space is initialized to zero.
-.Pp
-The
-.Fn realloc
-function changes the size of the object pointed to by
-.Fa ptr
-to
-.Fa size
-bytes and returns a pointer to the (possibly moved) object.
-If
-.Fa ptr
-is not
-.Dv NULL ,
-it must be a pointer returned by an earlier call to an allocation or
-reallocation function that was not freed in between.
-The contents of the object are unchanged up to the lesser
-of the new and old sizes.
-If the new size is larger, the value of the newly allocated portion
-of the object is indeterminate and uninitialized.
-If the space cannot be allocated, the object
-pointed to by
-.Fa ptr
-is unchanged.
-If
-.Fa ptr
-is
-.Dv NULL ,
-.Fn realloc
-behaves like
-.Fn malloc
-and allocates a new object.
-.Pp
-The
-.Fn free
-function causes the space pointed to by
-.Fa ptr
-to be either placed on a list of free blocks to make it available for future
-allocation or, when appropriate, to be returned to the kernel using
-.Xr munmap 2 .
-If
-.Fa ptr
-is
-.Dv NULL ,
-no action occurs.
-If
-.Fa ptr
-was previously freed by
-.Fn free
-or a reallocation function,
-the behavior is undefined and the double free is a security concern.
-.Pp
-Designed for safe allocation of arrays,
-the
-.Fn reallocarray
-function is similar to
-.Fn realloc
-except it operates on
-.Fa nmemb
-members of size
-.Fa size
-and checks for integer overflow in the calculation
-.Fa nmemb
-*
-.Fa size .
-.Pp
-Used for the allocation of memory holding sensitive data,
-the
-.Fn recallocarray
-and
-.Fn freezero
-functions guarantee that memory becoming unallocated is explicitly
-.Em discarded ,
-meaning pages of memory are disposed via
-.Xr munmap 2
-and cached free objects are cleared with
-.Xr explicit_bzero 3 .
-.Pp
-The
-.Fn recallocarray
-function is similar to
-.Fn reallocarray
-except it ensures newly allocated memory is cleared similar to
-.Fn calloc .
-If
-.Fa ptr
-is
-.Dv NULL ,
-.Fa oldnmemb
-is ignored and the call is equivalent to
-.Fn calloc .
-If
-.Fa ptr
-is not
-.Dv NULL ,
-.Fa oldnmemb
-must be a value such that
-.Fa oldnmemb
-*
-.Fa size
-is the size of the earlier allocation that returned
-.Fa ptr ,
-otherwise the behavior is undefined.
-.Pp
-The
-.Fn freezero
-function is similar to the
-.Fn free
-function except it ensures memory is explicitly discarded.
-If
-.Fa ptr
-is
-.Dv NULL ,
-no action occurs.
-If
-.Fa ptr
-is not
-.Dv NULL ,
-the
-.Fa size
-argument must be equal to or smaller than the size of the earlier allocation
-that returned
-.Fa ptr .
-.Fn freezero
-guarantees the memory range starting at
-.Fa ptr
-with length
-.Fa size
-is discarded while deallocating the whole object originally allocated.
-.Pp
-The
-.Fn aligned_alloc
-function allocates
-.Fa size
-bytes of memory such that the allocation's base address is a multiple of
-.Fa alignment .
-The requested
-.Fa alignment
-must be a power of 2.
-If
-.Fa size
-is not a multiple of
-.Fa alignment ,
-behavior is undefined.
-.Pp
-The
-.Fn malloc_conceal
-and
-.Fn calloc_conceal
-functions behave the same as
-.Fn malloc
-and
-.Fn calloc
-respectively,
-with the exception that the allocation returned is marked with the
-.Dv MAP_CONCEAL
-.Xr mmap 2
-flag and calling
-.Fn free
-on the allocation will discard the contents explicitly.
-A reallocation of a concealed allocation will leave these properties intact.
-.Sh MALLOC OPTIONS
-Upon the first call to the
-.Fn malloc
-family of functions, an initialization sequence inspects the
-value of the
-.Va vm.malloc_conf
-.Xr sysctl 2 ,
-next checks the environment for a variable called
-.Ev MALLOC_OPTIONS ,
-and finally looks at the global variable
-.Va malloc_options
-in the program.
-Each is scanned for the flags documented below.
-Unless otherwise noted uppercase means on, lowercase means off.
-During initialization, flags occurring later modify the behaviour
-that was requested by flags processed earlier.
-.Bl -tag -width indent
-.It Cm C
-.Dq Canaries .
-Add canaries at the end of allocations in order to detect
-heap overflows.
-The canary's content is checked when
-.Nm free
-is called.
-If it has been corrupted, the process is aborted.
-.It Cm D
-.Dq Dump .
-.Fn malloc
-will dump statistics to the file
-.Pa ./malloc.out ,
-if it already exists,
-at exit.
-This option requires the library to have been compiled with -DMALLOC_STATS in
-order to have any effect.
-.It Cm F
-.Dq Freecheck .
-Enable more extensive double free and use after free detection.
-All chunks in the delayed free list will be checked for double frees.
-Unused pages on the freelist are read and write protected to
-cause a segmentation fault upon access.
-.It Cm G
-.Dq Guard .
-Enable guard pages.
-Each page size or larger allocation is followed by a guard page that will
-cause a segmentation fault upon any access.
-.It Cm J
-.Dq More junking .
-Increase the junk level by one if it is smaller than 2.
-.It Cm j
-.Dq Less junking .
-Decrease the junk level by one if it is larger than 0.
-Junking writes some junk bytes into the area allocated.
-Junk is bytes of 0xdb when allocating;
-freed chunks are filled with 0xdf.
-By default the junk level is 1: after free,
-small chunks are completely junked;
-for pages the first part is junked.
-After a delay,
-the filling pattern is validated and the process is aborted if the pattern
-was modified.
-For junk level 2, junking is done on allocation as well and without size
-restrictions.
-If the junk level is zero, no junking is performed.
-.It Cm R
-.Dq realloc .
-Always reallocate when
-.Fn realloc
-is called, even if the initial allocation was big enough.
-.\".Pp
-.\".It Cm U
-.\".Dq utrace .
-.\"Generate entries for

-.\"for all operations.
-.\"Consult the source for this one.
-.It Cm S
-.\" Malloc option S is vaguely documented on purpose.
-Enable all options suitable for security auditing.
-.It Cm U
-.Dq Free unmap .
-Enable use after free protection for larger allocations.
-Unused pages on the freelist are read and write protected to
-cause a segmentation fault upon access.
-.It Cm X
-.Dq xmalloc .
-Rather than return failure,
-.Xr abort 3
-the program with a diagnostic message on stderr.
-It is the intention that this option be set at compile time by
-including in the source:
-.Bd -literal -offset indent
-extern char *malloc_options;
-malloc_options = "X";
-.Ed
-.Pp
-Note that this will cause code that is supposed to handle
-out-of-memory conditions gracefully to abort instead.
-.It Cm <
-.Dq Halve the cache size .
-Decrease the size of the free page cache by a factor of two.
-.It Cm >
-.Dq Double the cache size .
-Increase the size of the free page cache by a factor of two.
-.El
-.Pp
-If a program changes behavior if any of these options (except
-.Cm X )
-are used,
-it is buggy.
-.Pp
-The default size of the cache is 64 single page allocations.
-It also caches a number of larger regions.
-Multi-threaded programs use multiple pools.
-.Sh RETURN VALUES
-Upon successful completion, the allocation functions
-return a pointer to the allocated space; otherwise,
-.Dv NULL
-is returned and
-.Va errno
-is set to
-.Er ENOMEM .
-The function
-.Fn aligned_alloc
-returns
-.Dv NULL
-and sets
-.Va errno
-to
-.Er EINVAL
-if
-.Fa alignment
-is not a power of 2.
-.Pp
-If
-.Fa nmemb
-or
-.Fa size
-is equal to 0, a unique pointer to an access protected,
-zero sized object is returned.
-Access via this pointer will generate a
-.Dv SIGSEGV
-exception.
-.Pp
-If multiplying
-.Fa nmemb
-and
-.Fa size
-results in integer overflow,
-.Fn calloc ,
-.Fn reallocarray
-and
-.Fn recallocarray
-return
-.Dv NULL
-and set
-.Va errno
-to
-.Er ENOMEM .
-.Pp
-If
-.Fa ptr
-is not
-.Dv NULL
-and multiplying
-.Fa oldnmemb
-and
-.Fa size
-results in integer overflow
-.Fn recallocarray
-returns
-.Dv NULL
-and sets
-.Va errno
-to
-.Er EINVAL .
-.Sh IDIOMS
-Consider
-.Fn calloc
-or the extensions
-.Fn reallocarray
-and
-.Fn recallocarray
-when there is multiplication in the
-.Fa size
-argument of
-.Fn malloc
-or
-.Fn realloc .
-For example, avoid this common idiom as it may lead to integer overflow:
-.Bd -literal -offset indent
-if ((p = malloc(num * size)) == NULL)
-        err(1, NULL);
-.Ed
-.Pp
-A drop-in replacement is the
-.Ox
-extension
-.Fn reallocarray :
-.Bd -literal -offset indent
-if ((p = reallocarray(NULL, num, size)) == NULL)
-        err(1, NULL);
-.Ed
-.Pp
-Alternatively,
-.Fn calloc
-may be used at the cost of initialization overhead.
-.Pp
-When using
-.Fn realloc ,
-be careful to avoid the following idiom:
-.Bd -literal -offset indent
-size += 50;
-if ((p = realloc(p, size)) == NULL)
-        return (NULL);
-.Ed
-.Pp
-Do not adjust the variable describing how much memory has been allocated
-until the allocation has been successful.
-This can cause aberrant program behavior if the incorrect size value is used.
-In most cases, the above sample will also result in a leak of memory.
-As stated earlier, a return value of
-.Dv NULL
-indicates that the old object still remains allocated.
-Better code looks like this:
-.Bd -literal -offset indent
-newsize = size + 50;
-if ((newp = realloc(p, newsize)) == NULL) {
-        free(p);
-        p = NULL;
-        size = 0;
-        return (NULL);
-}
-p = newp;
-size = newsize;
-.Ed
-.Pp
-As with
-.Fn malloc ,
-it is important to ensure the new size value will not overflow;
-i.e. avoid allocations like the following:
-.Bd -literal -offset indent
-if ((newp = realloc(p, num * size)) == NULL) {
-        ...
-.Ed
-.Pp
-Instead, use
-.Fn reallocarray :
-.Bd -literal -offset indent
-if ((newp = reallocarray(p, num, size)) == NULL) {
-        ...
-.Ed
-.Pp
-Calling
-.Fn realloc
-with a
-.Dv NULL
-.Fa ptr
-is equivalent to calling
-.Fn malloc .
-Instead of this idiom:
-.Bd -literal -offset indent
-if (p == NULL)
-        newp = malloc(newsize);
-else
-        newp = realloc(p, newsize);
-.Ed
-.Pp
-Use the following:
-.Bd -literal -offset indent
-newp = realloc(p, newsize);
-.Ed
-.Pp
-The
-.Fn recallocarray
-function should be used for resizing objects containing sensitive data like
-keys.
-To avoid leaking information,
-it guarantees memory is cleared before placing it on the internal free list.
-Deallocation of such an object should be done by calling
-.Fn freezero .
-.Sh ENVIRONMENT
-.Bl -tag -width "MALLOC_OPTIONS"
-.It Ev MALLOC_OPTIONS
-String of option flags.
-.El
-.Sh EXAMPLES
-If
-.Fn malloc
-must be used with multiplication, be sure to test for overflow:
-.Bd -literal -offset indent
-size_t num, size;
-\&...
-
-/* Check for size_t overflow */
-if (size && num > SIZE_MAX / size)
-        errc(1, EOVERFLOW, "overflow");
-
-if ((p = malloc(num * size)) == NULL)
-        err(1, NULL);
-.Ed
-.Pp
-The above test is not sufficient in all cases.
-For example, multiplying ints requires a different set of checks:
-.Bd -literal -offset indent
-int num, size;
-\&...
-
-/* Avoid invalid requests */
-if (size < 0 || num < 0)
-        errc(1, EOVERFLOW, "overflow");
-
-/* Check for signed int overflow */
-if (size && num > INT_MAX / size)
-        errc(1, EOVERFLOW, "overflow");
-
-if ((p = malloc(num * size)) == NULL)
-        err(1, NULL);
-.Ed
-.Pp
-Assuming the implementation checks for integer overflow as
-.Ox
-does, it is much easier to use
-.Fn calloc ,
-.Fn reallocarray ,
-or
-.Fn recallocarray .
-.Pp
-The above examples could be simplified to:
-.Bd -literal -offset indent
-if ((p = reallocarray(NULL, num, size)) == NULL)
-        err(1, NULL);
-.Ed
-.Pp
-or at the cost of initialization:
-.Bd -literal -offset indent
-if ((p = calloc(num, size)) == NULL)
-        err(1, NULL);
-.Ed
-.Pp
-Set a systemwide reduction of the cache to a quarter of the
-default size and use guard pages:
-.Pp
-.Dl # sysctl vm.malloc_conf='G<<'
-.Sh DIAGNOSTICS
-If any of the functions detect an error condition,
-a message will be printed to file descriptor
-2 (not using stdio).
-Errors will result in the process being aborted.
-.Pp
-Here is a brief description of the error messages and what they mean:
-.Bl -tag -width Ds
-.It Dq out of memory
-If the
-.Cm X
-option is specified it is an error for the allocation functions
-to return
-.Dv NULL .
-.It Dq bogus pointer (double free?)
-An attempt to
-.Fn free
-or
-reallocate an unallocated pointer was made.
-.It Dq chunk is already free
-There was an attempt to free a chunk that had already been freed.
-.It Dq write after free
-A chunk has been modified after it was freed.
-.It Dq modified chunk-pointer
-The pointer passed to
-.Fn free
-or a reallocation function has been modified.
-.It Dq chunk canary corrupted address offset@length
-A byte after the requested size has been overwritten,
-indicating a heap overflow.
-The offset at which corruption was detected is printed before the @,
-and the requested length of the allocation after the @.
-.It Dq recorded old size oldsize != size
-.Fn recallocarray
-has detected that the given old size does not equal the recorded size in its
-meta data.
-Enabling option
-.Cm C
-allows
-.Fn recallocarray
-to catch more of these cases.
-.It Dq recursive call
-An attempt was made to call recursively into these functions, i.e., from a
-signal handler.
-This behavior is not supported.
-In particular, signal handlers should
-.Em not
-use any of the
-.Fn malloc
-functions nor utilize any other functions which may call
-.Fn malloc
-(e.g.,
-.Xr stdio 3
-routines).
-.It Dq unknown char in MALLOC_OPTIONS
-We found something we didn't understand.
-.It any other error
-.Fn malloc
-detected an internal error;
-consult sources and/or wizards.

-The

-function conforms to

-.Sh HISTORY
-A
-.Fn free
-internal kernel function and a predecessor to
-.Fn malloc ,
-.Fn alloc ,
-first appeared in
-.At v1 .
-C library functions
-.Fn alloc
-and
-.Fn free
-appeared in
-.At v6 .
-The functions
-.Fn malloc ,
-.Fn calloc ,
-and
-.Fn realloc
-first appeared in
-.At v7 .
-.Pp
-A new implementation by Chris Kingsley was introduced in
-.Bx 4.2 ,
-followed by a complete rewrite by Poul-Henning Kamp which appeared in
-.Fx 2.2
-and was included in
-.Ox 2.0 .
-These implementations were all
-.Xr sbrk 2
-based.
-In
-.Ox 3.8 ,
-Thierry Deval rewrote
-.Nm
-to use the
-.Xr mmap 2
-system call,
-making the page addresses returned by
-.Nm
-random.
-A rewrite by Otto Moerbeek introducing a new central data structure and more
-randomization appeared in
-.Ox 4.4 .
-.Pp
-The
-.Fn reallocarray
-function appeared in
-.Ox 5.6 .
-The
-.Fn recallocarray
-function appeared in
-.Ox 6.1 .
-The
-.Fn freezero
-function appeared in
-.Ox 6.2 .
-The
-.Fn aligned_alloc
-function appeared in
-.Ox 6.5 .
-The
-.Fn malloc_conceal
-and
-.Fn calloc_conceal
-functions appeared in
-.Ox 6.6 .
-.Sh CAVEATS
-When using
-.Fn malloc ,
-be wary of signed integer and
-.Vt size_t
-overflow especially when there is multiplication in the
-.Fa size
-argument.
-.Pp
-Signed integer overflow will cause undefined behavior which compilers
-typically handle by wrapping back around to negative numbers.
-Depending on the input, this can result in allocating more or less
-memory than intended.
-.Pp
-An unsigned overflow has defined behavior which will wrap back around and
-return less memory than intended.
-.Pp
-A signed or unsigned integer overflow is a
-.Em security
-risk if less memory is returned than intended.
-Subsequent code may corrupt the heap by writing beyond the memory that was
-allocated.
-An attacker may be able to leverage this heap corruption to execute arbitrary
-code.
-.Pp
-Consider using
-.Fn calloc ,
-.Fn reallocarray
-or
-.Fn recallocarray
-instead of using multiplication in
-.Fn malloc
-and
-.Fn realloc
-to avoid these problems on
-.Ox .

-.Sh DESCRIPTION
-The
-.Fn grantpt ,
-.Fn ptsname ,
-and
-.Fn unlockpt
-functions allow access to pseudo-terminal devices.
-These three functions accept a file descriptor that references the
-master half of a pseudo-terminal pair.
-This file descriptor is created with
-.Xr posix_openpt 3 .
-.Pp
-The
-.Fn grantpt
-function is used to establish ownership and permissions
-of the slave device counterpart to the master device
-specified with
-.Fa fildes .
-The slave device's ownership is set to the real user ID
-of the calling process, and the permissions are set to
-user readable-writable and group writable.
-The group owner of the slave device is also set to the
-group
-.Dq Li tty .
-.Pp
-The
-.Fn ptsname
-function returns the full path name of the slave device
-counterpart to the master device specified with
-.Fa fildes .
-This value can be used
-to subsequently open the appropriate slave after
-.Xr posix_openpt 3
-and
-.Fn grantpt
-have been called.
-.Pp
-The
-.Fn unlockpt
-function clears the lock held on the pseudo-terminal pair
-for the master device specified with
-.Fa fildes .
-.Sh RETURN VALUES
-.Rv -std grantpt unlockpt
-.Pp
-The
-.Fn ptsname
-function returns a pointer to the name
-of the slave device on success; otherwise a

-.Pp
-This implementation of
-.Fn grantpt
-and
-.Fn unlockpt
-does not conform to
-.St -p1003.1-2008 ,
-because it depends on
-.Xr posix_openpt 3

-.Os
-.Sh NAME
-.Nm qsort ,
-.Nm heapsort ,
-.Nm mergesort
-.Nd sort functions
-.Sh SYNOPSIS
-.In stdlib.h
-.Ft void
-.Fn qsort "void *base" "size_t nmemb" "size_t size" "int (*compar)(const void *, const void *)"
-.Ft int
-.Fn heapsort "void *base" "size_t nmemb" "size_t size" "int (*compar)(const void *, const void *)"
-.Ft int
-.Fn mergesort "void *base" "size_t nmemb" "size_t size" "int (*compar)(const void *, const void *)"
-.Sh DESCRIPTION
-The
-.Fn qsort
-function is a modified partition-exchange sort, or quicksort.
-The
-.Fn heapsort
-function is a modified selection sort.
-The
-.Fn mergesort
-function is a modified merge sort with exponential search
-intended for sorting data with pre-existing order.
-.Pp
-The
-.Fn qsort
-and
-.Fn heapsort
-functions sort an array of
-.Fa nmemb
-objects, the initial member of which is pointed to by
-.Fa base .
-The size of each object is specified by
-.Fa size .
-.Fn mergesort
-behaves similarly, but
-.Em requires
-that
-.Fa size
-be greater than
-.Dq "sizeof(void *) / 2" .
-.Pp
-The contents of the array
-.Fa base
-are sorted in ascending order according to
-a comparison function pointed to by
-.Fa compar ,
-which requires two arguments pointing to the objects being
-compared.
-.Pp
-The comparison function must return an int less than, equal to, or
-greater than zero if the first argument is considered to be respectively
-less than, equal to, or greater than the second.
-.Pp
-The functions
-.Fn qsort
-and
-.Fn heapsort
-are
-.Em not
-stable, that is, if two members compare as equal, their order in
-the sorted array is undefined.
-The function
-.Fn mergesort
-is stable.
-.Pp
-The
-.Fn qsort
-function is an implementation of C.A.R. Hoare's
-.Dq quicksort
-algorithm,
-a variant of partition-exchange sorting; in particular, see D.E. Knuth's
-Algorithm Q.
-.Fn qsort
-takes O N lg N average time.
-This implementation uses median selection to avoid its
-O N**2 worst-case behavior and will fall back to
-.Fn heapsort
-if the recursion depth exceeds 2 lg N.
-.Pp
-The
-.Fn heapsort
-function is an implementation of J.W.J. William's
-.Dq heapsort
-algorithm,
-a variant of selection sorting; in particular, see D.E. Knuth's Algorithm H.
-.Fn heapsort
-takes O N lg N worst-case time.
-This implementation of
-.Fn heapsort
-is implemented without recursive function calls.
-.Pp
-The function
-.Fn mergesort
-requires additional memory of size
-.Fa nmemb *
-.Fa size
-bytes; it should be used only when space is not at a premium.
-.Fn mergesort
-is optimized for data with pre-existing order; its worst case
-time is O N lg N; its best case is O N.
-.Pp
-Normally,
-.Fn qsort
-is faster than
-.Fn mergesort ,
-which is faster than
-.Fn heapsort .
-Memory availability and pre-existing order in the data can make this untrue.
-.Sh RETURN VALUES
-.Rv -std heapsort mergesort
-.Sh EXAMPLES
-.Bd -literal
-#include <stdio.h>
-#include <stdlib.h>
-#include <string.h>

-         */
-        size_t lena = strlen(*(const char **)a);
-        size_t lenb = strlen(*(const char **)b);
-        /*
-         * Do not subtract the lengths. The difference between values
-         * cannot be represented by an int.

-It is almost always an error to use subtraction to compute the return value
-of the comparison function.

- * Qsort routine from Bentley & McIlroy's "Engineering a Sort Function".
- *
- * This version differs from Bentley & McIlroy in the following ways:
- *   1. The partition value is swapped into a[0] instead of being
- *      stored out of line.
- *
- *   2. The swap function can swap 32-bit aligned elements on 64-bit
- *      platforms instead of swapping them as byte-aligned.
- *
- *   3. It uses David Musser's introsort algorithm to fall back to
- *      heapsort(3) when the recursion depth reaches 2*lg(n + 1).
- *      This avoids quicksort's quadratic behavior for pathological
- *      input without appreciably changing the average run time.
- *
- *   4. Tail recursion is eliminated when sorting the larger of two
- *      subpartitions to save stack space.

-.Sh NAME
-.Nm radixsort ,
-.Nm sradixsort
-.Nd radix sort
-.Sh SYNOPSIS
-.In limits.h
-.In stdlib.h
-.Ft int
-.Fn radixsort "const u_char **base" "int nmemb" "const u_char *table" "u_int endbyte"
-.Ft int
-.Fn sradixsort "const u_char **base" "int nmemb" "const u_char *table" "u_int endbyte"
-.Sh DESCRIPTION
-The
-.Fn radixsort
-and
-.Fn sradixsort
-functions are implementations of radix sort.
-.Pp
-These functions sort an array of
-.Fa nmemb
-pointers to byte strings.
-The initial member is referenced by
-.Fa base .
-The byte strings may contain any values; the end of each string
-is denoted by the user-specified value
-.Fa endbyte .
-.Pp
-Applications may specify a sort order by providing the
-.Fa table
-argument.
-If non-null,
-.Fa table
-must reference an array of
-.Dv UCHAR_MAX
-+ 1 bytes which contains the sort weight of each possible byte value.
-The end-of-string byte must have a sort weight of 0 or 255
-(for sorting in reverse order).
-More than one byte may have the same sort weight.
-The
-.Fa table
-argument is useful for applications which wish to sort different characters
-equally; for example, providing a table with the same weights
-for A\-Z as for a\-z will result in a case-insensitive sort.
-If
-.Fa table
-is
-.Dv NULL ,
-the contents of the array are sorted in ascending order according to the
-ASCII order of the byte strings they reference and
-.Fa endbyte
-has a sorting weight of 0.
-.Pp
-The
-.Fn sradixsort
-function is stable; that is, if two elements compare as equal, their
-order in the sorted array is unchanged.
-The
-.Fn sradixsort
-function uses additional memory sufficient to hold
-.Fa nmemb
-pointers.
-.Pp
-The
-.Fn radixsort
-function is not stable, but uses no additional memory.
-.Pp
-These functions are variants of most-significant-byte radix sorting; in
-particular, see D.E. Knuth's Algorithm R and section 5.2.5, exercise 10.
-They take linear time relative to the number of bytes in the strings.
-.Sh RETURN VALUES
-.Rv -std
-.Sh ERRORS
-.Bl -tag -width Er
-.It Bq Er EINVAL
-The value of the
-.Fa endbyte
-element of
-.Fa table
-is not 0 or 255.
-.El
-.Pp
-Additionally, the
-.Fn sradixsort
-function may fail and set
-.Va errno
-for any of the errors specified for the library routine
-.Xr malloc 3 .

-.Sh DESCRIPTION
-.Bf -symbolic
-Standards insist that this interface return deterministic results.
-Unsafe usage is very common, so
-.Ox
-changed the subsystem to return non-deterministic results by default.
-.Ef
-.Pp
-To satisfy portable code,
-.Fn srand48 ,
-.Fn seed48 ,
-or
-.Fn lcong48
-should be called to initialize the subsystem.
-In
-.Ox
-the
-seeding parameters are ignored, and strong random number results will be
-provided from
-.Xr arc4random 3 .
-In other systems, the
-parameters prime a simplistic deterministic algorithm.
-.Pp
-If the standardized behavior is required then
-.Fn srand48_deterministic ,
-.Fn seed48_deterministic ,
-and
-.Fn lcong48_deterministic
-can be substituted for
-.Fn srand48 ,
-.Fn seed48 ,
-and
-.Fn lcong48 .
-That will cause subsequent
-calls to
-.Fn drand48 ,
-.Fn lrand48 ,
-and
-.Fn jrand48
-to return results using the deterministic algorithm.
-.Pp
-.Fn drand48
-and
-.Fn erand48
-return values of type double.
-The full 48 bits of r(n+1) are
-loaded into the mantissa of the returned value, with the exponent set
-such that the values produced lie in the interval [0.0, 1.0).
-.Pp
-.Fn lrand48
-and
-.Fn nrand48
-return values of type long in the range
-[0, 2**31-1].
-The high-order (31) bits of
-r(n+1) are loaded into the lower bits of the returned value, with
-the topmost (sign) bit set to zero.
-.Pp
-.Fn mrand48
-and
-.Fn jrand48
-return values of type long in the range
-[-2**31, 2**31-1].
-The high-order (32) bits of r(n+1) are loaded into the returned value.
-.Pp
-In the deterministic mode, the
-.Fn rand48
-family of functions generates numbers using a linear congruential
-algorithm working on integers 48 bits in size.
-The particular formula employed is
-r(n+1) = (a * r(n) + c) mod m
-where the default values are
-for the multiplicand a = 0xfdeece66d = 25214903917 and
-the addend c = 0xb = 11.
-The modulus is always fixed at m = 2 ** 48.
-r(n) is called the seed of the random number generator.
-.Pp
-For all the six generator routines described next, the first
-computational step is to perform a single iteration of the algorithm.
-.Pp
-.Fn drand48 ,
-.Fn lrand48 ,
-and
-.Fn mrand48
-use an internal buffer to store r(n).
-For these functions
-the initial value of r(0) = 0x1234abcd330e = 20017429951246.
-.Pp
-On the other hand,
-.Fn erand48 ,
-.Fn nrand48 ,
-and
-.Fn jrand48
-use a user-supplied buffer to store the seed r(n),
-which consists of an array of 3 shorts, where the zeroth member
-holds the least significant bits.
-.Pp
-All functions share the same multiplicand and addend.
-.Pp
-.Fn srand48_deterministic
-is used to initialize the internal buffer r(n) of
-.Fn drand48 ,
-.Fn lrand48 ,
-and
-.Fn mrand48
-such that the 32 bits of the seed value are copied into the upper 32 bits
-of r(n), with the lower 16 bits of r(n) arbitrarily being set to 0x330e.
-Additionally, the constant multiplicand and addend of the algorithm are
-reset to the default values given above.
-.Pp
-.Fn seed48_deterministic
-also initializes the internal buffer r(n) of
-.Fn drand48 ,
-.Fn lrand48 ,
-and
-.Fn mrand48 ,
-but here all 48 bits of the seed can be specified in an array of 3 shorts,
-where the zeroth member specifies the lowest bits.
-Again, the constant multiplicand and addend of the algorithm are
-reset to the default values given above.
-.Fn seed48_deterministic
-returns a pointer to an array of 3 shorts which contains the old seed.
-This array is statically allocated, so its contents are lost after
-each new call to
-.Fn seed48_deterministic .
-.Pp
-Finally,
-.Fn lcong48_deterministic
-allows full control over the multiplicand and addend used in
-.Fn drand48 ,
-.Fn erand48 ,
-.Fn lrand48 ,
-.Fn nrand48 ,
-.Fn mrand48 ,
-and
-.Fn jrand48 ,
-and the seed used in
-.Fn drand48 ,
-.Fn lrand48 ,
-and
-.Fn mrand48 .
-An array of 7 shorts is passed as parameter; the first three shorts are
-used to initialize the seed; the second three are used to initialize the
-multiplicand; and the last short is used to initialize the addend.
-It is thus not possible to use values greater than 0xffff as the addend.
-.Pp
-Note that all three methods of seeding the random number generator
-always also set the multiplicand and addend for any of the six
-generator calls.

-.Pp
-In non-deterministic (default) mode, the
-.Fn random
-function returns results from
-.Xr arc4random 3
-in the range from 0 to (2**31)\-1.
-.Pp
-In deterministic mode, the
-.Fn random
-function uses a non-linear additive feedback random number generator employing
-a default table of size 31 long integers to return successive pseudo-random
-numbers in the range from 0 to (2**31)\-1.
-The period of this random number generator is very large, approximately
-16*((2**31)\-1), but the results are a deterministic sequence from the seed.
-The deterministic sequence algorithm changed a number of times since
-original development, is underspecified, and should not be relied upon to
-remain consistent between platforms and over time.
-.Pp
-The
-.Fn initstate
-routine allows a state array, passed in as an argument, to be initialized
-for future use.
-The size of the state array (in bytes) is used by
-.Fn initstate
-to decide how sophisticated a random number generator it should use \(em the
-more state, the better the random numbers will be.
-(Current "optimal" values for the amount of state information are
-8, 32, 64, 128, and 256 bytes; other amounts will be rounded down to
-the nearest known amount.
-Using less than 8 bytes will cause an error.)
-The seed for the initialization (which specifies a starting point for
-the random number sequence, and provides for restarting at the same
-point) is also an argument.
-The
-.Fn initstate
-function returns a pointer to the previous state information array.
-.Pp
-Once a state has been initialized, the
-.Fn setstate
-routine provides for rapid switching between states.
-The
-.Fn setstate
-function returns a pointer to the previous state array; its
-argument state array is used for further random number generation
-until the next call to
-.Fn initstate
-or
-.Fn setstate .
-.Pp
-Once a state array has been initialized, it may be restarted at a
-different point either by calling
-.Fn initstate
-(with the desired seed, the state array, and its size) or by calling
-both
-.Fn setstate
-(with the state array) and
-.Fn srandom
-(with the desired seed).
-The advantage of calling both
-.Fn setstate
-and
-.Fn srandom
-is that the size of the state array does not have to be remembered after
-it is initialized.
-.Pp
-Use of
-.Fn srandom_deterministic ,
-.Fn initstate ,
-or
-.Fn setstate
-forces the subsystem into deterministic mode.
-.Sh DIAGNOSTICS

- * random.c:
- *
- * An improved random number generation package.  In addition to the standard
- * rand()/srand() like interface, this package also has a special state info
- * interface.  The initstate() routine is called with a seed, an array of
- * bytes, and a count of how many bytes are being passed in; this array is
- * then initialized to contain information for random number generation with
- * that much state information.  Good sizes for the amount of state
- * information are 32, 64, 128, and 256 bytes.  The state can be switched by
- * calling the setstate() routine with the same array as was initiallized
- * with initstate().  By default, the package runs with 128 bytes of state
- * information and generates far better random numbers than a linear
- * congruential generator.  If the amount of state information is less than
- * 32 bytes, a simple linear congruential R.N.G. is used.
- *
- * Internally, the state information is treated as an array of int32_t; the
- * zeroeth element of the array is the type of R.N.G. being used (small
- * integer); the remainder of the array is the state information for the
- * R.N.G.  Thus, 32 bytes of state information will give 7 int32_ts worth of
- * state information, which will allow a degree seven polynomial.  (Note:
- * the zeroeth word of state information also has some other information
- * stored in it -- see setstate() for details).
- * 
- * The random number generation technique is a linear feedback shift register
- * approach, employing trinomials (since there are fewer terms to sum up that
- * way).  In this approach, the least significant bit of all the numbers in
- * the state table will act as a linear feedback shift register, and will
- * have period 2^deg - 1 (where deg is the degree of the polynomial being
- * used, assuming that the polynomial is irreducible and primitive).  The
- * higher order bits will have longer periods, since their values are also
- * influenced by pseudo-random carries out of the lower bits.  The total
- * period of the generator is approximately deg*(2**deg - 1); thus doubling
- * the amount of state information has a vast influence on the period of the
- * generator.  Note: the deg*(2**deg - 1) is an approximation only good for
- * large deg, when the period of the shift register is the dominant factor.
- * With deg equal to seven, the period is actually much longer than the
- * 7*(2**7 - 1) predicted by this formula.
- */
-
-/*
- * For each of the currently supported random number generators, we have a
- * break value on the amount of state information (you need at least this

-.Pa /../
-in
-.Fa pathname ,
-and copies the resulting absolute pathname into the memory referenced by
-.Fa resolved .
-The
-.Fa resolved
-argument
-.Em must
-refer to a buffer capable of storing at least
-.Dv PATH_MAX
-characters, or be
-.Dv NULL .
-.Pp
-The
-.Fn realpath
-function will resolve both absolute and relative paths
-and return the absolute pathname corresponding to
-.Fa pathname .
-All components of
-.Fa pathname
-must exist when
-.Fn realpath
-is called.
-.Sh RETURN VALUES
-The
-.Fn realpath
-function returns
-.Fa resolved
-on success.
-If
-.Fa resolved
-is
-.Dv NULL
-and no error occurred, then
-.Fn realpath
-returns a NUL-terminated string in a newly allocated buffer.
-If an error occurs,
-.Fn realpath
-returns
-.Dv NULL
-and the contents of
-.Fa resolved
-are undefined.
-.Sh ERRORS
-The function
-.Fn realpath
-will fail if:
-.Bl -tag -width Er
-.It Bq Er EACCES
-Read or search permission was denied for a component of
-.Ar pathname .
-.It Bq Er EINVAL
-The
-.Ar pathname
-argument is a null pointer.
-.It Bq Er EIO
-An error occurred while reading from the file system.
-.It Bq Er ELOOP
-Too many symbolic links were encountered in translating
-.Ar pathname .
-.It Bq Er ENAMETOOLONG
-A component of
-.Ar pathname
-exceeded
-.Dv NAME_MAX
-characters, or the entire
-.Ar pathname
-(including the terminating NUL) exceeded
-.Dv PATH_MAX .
-.It Bq Er ENAMETOOLONG
-Pathname resolution of a symbolic link produced an intermediate
-result whose length exceeds
-.Dv PATH_MAX .
-.It Bq Er ENOENT
-A component of
-.Ar pathname
-does not name an existing file or
-.Ar pathname
-points to an empty string.
-.It Bq Er ENOTDIR
-A component of the path prefix is not a directory.

-.Sh NAME
-.Nm strtod ,
-.Nm strtof ,
-.Nm strtold
-.Nd convert ASCII string to double, float or long double
-.Sh SYNOPSIS
-.In stdlib.h
-.Ft double
-.Fn strtod "const char *nptr" "char **endptr"
-.Pp
-.Ft float
-.Fn strtof "const char *nptr" "char **endptr"
-.Pp
-.Ft long double
-.Fn strtold "const char *nptr" "char **endptr"
-.Sh DESCRIPTION
-The
-.Fn strtod
-function converts the initial portion of the string pointed to by
-.Fa nptr
-to
-.Li double
-representation.
-The
-.Fn strtof
-function converts the initial portion of the string pointed to by
-.Fa nptr
-to
-.Li float
-representation.
-The
-.Fn strtold
-function converts the initial portion of the string pointed to by
-.Fa nptr
-to
-.Li long double
-representation.
-.Pp
-The expected form of the string is an optional plus
-.Pq Ql +
-or minus sign
-.Pq Ql -
-followed by a sequence of digits optionally containing
-a decimal-point character, optionally followed by an exponent.
-An exponent consists of an
-.Sq E
-or
-.Sq e ,
-followed by an optional plus or minus sign, followed by a sequence of digits.
-.Pp
-Alternatively, if the portion of the string following the optional
-plus or minus sign begins with
-.Dq INF
-or
-.Dq NAN ,
-ignoring case, it is interpreted as an infinity or a quiet \*(Na,
-respectively.
-The syntax
-.Dq NAN Ns Pq Ar s ,
-where
-.Ar s
-is an alphanumeric string, produces the same value as the call
-.Fo nan
-.Qq Ar s Ns
-.Fc
-(respectively,
-.Fo nanf
-.Qq Ar s Ns
-.Fc
-and
-.Fo nanl
-.Qq Ar s Ns
-.Fc ) .
-.Pp
-In any of the above cases, leading whitespace characters in the
-string (as defined by the
-.Xr isspace 3
-function) are skipped.
-.Sh RETURN VALUES
-The
-.Fn strtod ,
-.Fn strtof
-and
-.Fn strtold
-functions return the converted value, if any.
-.Pp
-If
-.Fa endptr
-is not
-.Dv NULL ,
-a pointer to the character after the last character used
-in the conversion is stored in the location referenced by
-.Fa endptr .
-.Pp
-If no conversion is performed, zero is returned and the value of
-.Fa nptr
-is stored in the location referenced by
-.Fa endptr .
-.Pp
-If the correct value would cause overflow, plus or minus
-.Dv HUGE_VAL
-is returned (according to the sign of the value), and
-.Er ERANGE
-is stored in
-.Va errno .
-If the correct value would cause underflow, zero is returned and
-.Er ERANGE
-is stored in
-.Va errno .
-.Sh ERRORS
-.Bl -tag -width Er
-.It Bq Er ERANGE
-Overflow or underflow occurred.
-.El
-.Sh SEE ALSO
-.Xr atof 3 ,
-.Xr atoi 3 ,
-.Xr atol 3 ,
-.Xr strtol 3 ,
-.Xr strtoul 3
-.Sh STANDARDS
-The
-.Fn strtod
-function conforms to
-.St -ansiC-89 .
-The
-.Fn strtof
-and
-.Fn strtold
-functions conform to
-.St -isoC-99 .
-.Sh CAVEATS
-On systems other than
-.Ox ,
-the
-.Dv LC_NUMERIC
-.Xr locale 1
-category can cause parsing failures; see CAVEATS in
-.Xr setlocale 3
-for details.

-.Dt STRTOL 3
-.Os
-.Sh NAME
-.Nm strtol ,
-.Nm strtoll ,
-.Nm strtoimax ,
-.Nm strtoq
-.Nd convert string value to a long, long long or intmax_t integer
-.Sh SYNOPSIS
-.In limits.h
-.In stdlib.h
-.Ft long
-.Fn strtol "const char *nptr" "char **endptr" "int base"
-.Ft long long
-.Fn strtoll "const char *nptr" "char **endptr" "int base"
-.In inttypes.h
-.Ft intmax_t
-.Fn strtoimax "const char *nptr" "char **endptr" "int base"
-.In sys/types.h
-.In limits.h
-.In stdlib.h
-.Ft quad_t
-.Fn strtoq "const char *nptr" "char **endptr" "int base"
-.Sh DESCRIPTION
-The
-.Fn strtol
-function converts the string in
-.Fa nptr
-to a
-.Vt long
-value.
-The
-.Fn strtoll
-function converts the string in
-.Fa nptr
-to a
-.Vt long long
-value.
-The
-.Fn strtoimax
-function converts the string in
-.Fa nptr
-to an
-.Vt intmax_t
-value.
-The
-.Fn strtoq
-function is a deprecated equivalent of
-.Fn strtoll
-and is provided for backwards compatibility with legacy programs.
-The conversion is done according to the given
-.Fa base ,
-which must be a number between 2 and 36 inclusive or the special value 0.
-.Pp
-The string may begin with an arbitrary amount of whitespace
-(as determined by
-.Xr isspace 3 )
-followed by a single optional
-.Ql +
-or
-.Ql -
-sign.
-If
-.Fa base
-is zero or 16, the string may then include a
-.Ql 0x
-prefix, and the number will be read in base 16; otherwise, a zero
-.Fa base
-is taken as 10 (decimal) unless the next character is
-.Ql 0 ,
-in which case it is taken as 8 (octal).
-.Pp
-The remainder of the string is converted to a
-.Vt long ,
-.Vt long long ,
-or
-.Vt intmax_t
-value in the obvious manner,
-stopping at the first character which is not a valid digit
-in the given base.
-(In bases above 10, the letter
-.Ql A
-in either upper or lower case represents 10,
-.Ql B
-represents 11, and so forth, with
-.Ql Z
-representing 35.)
-.Pp
-If
-.Fa endptr
-is non-null,
-.Fn strtol
-stores the address of the first invalid character in
-.Fa *endptr .
-If there were no digits at all, however,
-.Fn strtol
-stores the original value of
-.Fa nptr
-in
-.Fa *endptr .
-(Thus, if
-.Fa *nptr
-is not
-.Ql \e0
-but
-.Fa **endptr
-is
-.Ql \e0
-on return, the entire string was valid.)
-.Sh RETURN VALUES
-The
-.Fn strtol ,
-.Fn strtoll ,
-.Fn strtoimax ,
-and
-.Fn strtoq
-functions return the result of the conversion.
-If overflow or underflow occurs,
-.Va errno
-is set to
-.Er ERANGE
-and the function return value is as follows:
-.Bl -column "strtoimaxXX" "INTMAX_MIN" "INTMAX_MAX" -offset indent
-.It Sy Function Ta Sy underflow Ta Sy overflow
-.It Fn strtol Ta Dv LONG_MIN Ta Dv LONG_MAX
-.It Fn strtoll Ta Dv LLONG_MIN Ta Dv LLONG_MAX
-.It Fn strtoimax Ta Dv INTMAX_MIN Ta Dv INTMAX_MAX
-.It Fn strtoq Ta Dv LLONG_MIN Ta Dv LLONG_MAX
-.El
-.Pp
-If there is no valid digit, 0 is returned.
-If
-.Ar base
-is invalid, 0 is returned and the global variable
-.Va errno
-is set to
-.Er EINVAL .
-.Sh EXAMPLES
-Ensuring that a string is a valid number (i.e., in range and containing no
-trailing characters) requires clearing
-.Va errno
-beforehand explicitly since
-.Va errno
-is not changed on a successful call to
-.Fn strtol ,
-and the return value of
-.Fn strtol
-cannot be used unambiguously to signal an error:
-.Bd -literal -offset indent
-char *ep;
-long lval;
-
-\&...
-
-errno = 0;
-lval = strtol(buf, &ep, 10);
-if (buf[0] == '\e0' || *ep != '\e0')
-        goto not_a_number;
-if (errno == ERANGE && (lval == LONG_MAX || lval == LONG_MIN))
-        goto out_of_range;
-.Ed
-.Pp
-This example will accept
-.Dq 12
-but not
-.Dq 12foo
-or
-.Dq 12\en .
-If trailing whitespace is acceptable, further checks must be done on
-.Va *ep ;
-alternately, use
-.Xr sscanf 3 .
-.Pp
-If
-.Fn strtol
-is being used instead of
-.Xr atoi 3 ,
-error checking is further complicated because the desired return value is an
-.Vt int
-rather than a
-.Vt long ;
-however, on some architectures integers and long integers are the same size.
-Thus the following is necessary:
-.Bd -literal -offset indent
-char *ep;
-int ival;
-long lval;
-
-\&...
-
-errno = 0;
-lval = strtol(buf, &ep, 10);
-if (buf[0] == '\e0' || *ep != '\e0')
-     goto not_a_number;
-if ((errno == ERANGE && (lval == LONG_MAX || lval == LONG_MIN)) ||
-    (lval > INT_MAX || lval < INT_MIN))
-     goto out_of_range;
-ival = lval;
-.Ed
-.Sh ERRORS
-.Bl -tag -width Er
-.It Bq Er EINVAL
-The value of
-.Ar base
-was neither between 2 and 36 inclusive nor the special value 0.
-.It Bq Er ERANGE
-The given string was out of range; the value converted has been clamped.

-.Dt STRTONUM 3
-.Os
-.Sh NAME
-.Nm strtonum
-.Nd reliably convert string value to an integer
-.Sh SYNOPSIS
-.In stdlib.h
-.Ft long long
-.Fo strtonum
-.Fa "const char *nptr"
-.Fa "long long minval"
-.Fa "long long maxval"
-.Fa "const char **errstr"
-.Fc
-.Sh DESCRIPTION
-The
-.Fn strtonum
-function converts the string in
-.Fa nptr
-to a
-.Li long long
-value.
-The
-.Fn strtonum
-function was designed to facilitate safe, robust programming
-and overcome the shortcomings of the
-.Xr atoi 3
-and
-.Xr strtol 3
-family of interfaces.
-.Pp
-The string may begin with an arbitrary amount of whitespace
-(as determined by
-.Xr isspace 3 )
-followed by a single optional
-.Ql +
-or
-.Ql -
-sign.
-.Pp
-The remainder of the string is converted to a
-.Li long long
-value according to base 10.
-.Pp
-The value obtained is then checked against the provided
-.Fa minval
-and
-.Fa maxval
-bounds.
-If
-.Fa errstr
-is non-null,
-.Fn strtonum
-stores an error string in
-.Fa *errstr
-indicating the failure.
-.Sh RETURN VALUES
-The
-.Fn strtonum
-function returns the result of the conversion,
-unless the value would exceed the provided bounds or is invalid.
-On error, 0 is returned,
-.Va errno
-is set, and
-.Fa errstr
-will point to an error message.
-.Fa *errstr
-will be set to
-.Dv NULL
-on success;
-this fact can be used to differentiate
-a successful return of 0 from an error.
-.Sh EXAMPLES
-Using
-.Fn strtonum
-correctly is meant to be simpler than the alternative functions.
-.Bd -literal -offset indent
-int iterations;
-const char *errstr;
-
-iterations = strtonum(optarg, 1, 64, &errstr);
-if (errstr != NULL)
-        errx(1, "number of iterations is %s: %s", errstr, optarg);
-.Ed
-.Pp
-The above example will guarantee that the value of iterations is between
-1 and 64 (inclusive).
-.Sh ERRORS
-.Bl -tag -width Er
-.It Bq Er ERANGE
-The given string was out of range.
-.It Bq Er EINVAL
-The given string did not consist solely of digit characters.
-.It Bq Er EINVAL
-.Ar minval
-was larger than
-.Ar maxval .
-.El
-.Pp
-If an error occurs,
-.Fa errstr
-will be set to one of the following strings:
-.Pp
-.Bl -tag -width "too largeXX" -compact
-.It Qq too large
-The result was larger than the provided maximum value.
-.It Qq too small
-The result was smaller than the provided minimum value.
-.It Qq invalid
-The string did not consist solely of digit characters.
-.El
-.Sh SEE ALSO
-.Xr atof 3 ,
-.Xr atoi 3 ,
-.Xr atol 3 ,
-.Xr atoll 3 ,
-.Xr sscanf 3 ,
-.Xr strtod 3 ,
-.Xr strtol 3 ,
-.Xr strtoul 3
-.Sh STANDARDS
-.Fn strtonum
-is an
-.Ox
-extension.
-The existing alternatives, such as
-.Xr atoi 3
-and
-.Xr strtol 3 ,
-are either impossible or difficult to use safely.
-.Sh HISTORY
-The
-.Fn strtonum
-function first appeared in
-.Ox 3.6 .

-.Os
-.Sh NAME
-.Nm strtoul ,
-.Nm strtoull ,
-.Nm strtoumax ,
-.Nm strtouq
-.Nd convert a string to an unsigned long, unsigned long long or uintmax_t integer
-.Sh SYNOPSIS
-.In limits.h
-.In stdlib.h
-.Ft unsigned long
-.Fn strtoul "const char *nptr" "char **endptr" "int base"
-.Ft unsigned long long
-.Fn strtoull "const char *nptr" "char **endptr" "int base"
-.In inttypes.h
-.Ft uintmax_t
-.Fn strtoumax "const char *nptr" "char **endptr" "int base"
-.In sys/types.h
-.In limits.h
-.In stdlib.h
-.Ft u_quad_t
-.Fn strtouq "const char *nptr" "char **endptr" "int base"
-.Sh DESCRIPTION
-The
-.Fn strtoul
-function converts the string in
-.Fa nptr
-to an
-.Vt unsigned long
-value.
-The
-.Fn strtoull
-function converts the string in
-.Fa nptr
-to an
-.Vt unsigned long long
-value.
-The
-.Fn strtoumax
-function converts the string in
-.Fa nptr
-to a
-.Vt umaxint_t
-value.
-The
-.Fn strtouq
-function is a deprecated equivalent of
-.Fn strtoull
-and is provided for backwards compatibility with legacy programs.
-The conversion is done according to the given
-.Fa base ,
-which must be a number between 2 and 36 inclusive or the special value 0.
-If the string in
-.Fa nptr
-represents a negative number, it will be converted to its unsigned equivalent.
-This behavior is consistent with what happens when a signed integer type is
-cast to its unsigned counterpart.
-.Pp
-The string may begin with an arbitrary amount of whitespace
-(as determined by
-.Xr isspace 3 )
-followed by a single optional
-.Ql +
-or
-.Ql -
-sign.
-If
-.Fa base
-is zero or 16, the string may then include a
-.Ql 0x
-prefix, and the number will be read in base 16; otherwise, a zero
-.Fa base
-is taken as 10 (decimal) unless the next character is
-.Ql 0 ,
-in which case it is taken as 8 (octal).
-.Pp
-The remainder of the string is converted to an
-.Vt unsigned long ,
-.Vt unsigned long long ,
-or
-.Vt uintmax_t
-value in the obvious manner,
-stopping at the first character which is not a valid digit
-in the given base.
-(In bases above 10, the letter
-.Ql A
-in either upper or lower case represents 10,
-.Ql B
-represents 11, and so forth, with
-.Ql Z
-representing 35.)
-.Pp
-If
-.Fa endptr
-is non-null,
-.Fn strtoul
-stores the address of the first invalid character in
-.Fa *endptr .
-If there were no digits at all, however,
-.Fn strtoul
-stores the original value of
-.Fa nptr
-in
-.Fa *endptr .
-(Thus, if
-.Fa *nptr
-is not
-.Ql \e0
-but
-.Fa **endptr
-is
-.Ql \e0
-on return, the entire string was valid.)
-.Sh RETURN VALUES
-The
-.Fn strtoul ,
-.Fn strtoull ,
-.Fn strtoumax
-and
-.Fn strtouq
-functions return either the result of the conversion or,
-if there was a leading minus sign,
-the negation of the result of the conversion,
-unless the original (non-negated) value would overflow.
-If overflow occurs,
-.Fn strtoul
-returns
-.Dv ULONG_MAX ,
-.Fn strtoull
-returns
-.Dv ULLONG_MAX ,
-.Fn strtoumax
-returns
-.Dv UINTMAX_MAX ,
-.Fn strtouq
-returns
-.Dv ULLONG_MAX
-and the global variable
-.Va errno
-is set to
-.Er ERANGE .
-.Pp
-There is no way to determine if
-.Fn strtoul
-has processed a negative number (and returned an unsigned value) short of
-examining the string in
-.Fa nptr
-directly.
-.Pp
-If there is no valid digit, 0 is returned.
-If
-.Ar base
-is invalid, 0 is returned and the global variable
-.Va errno
-is set to
-.Er EINVAL .
-.Sh EXAMPLES
-Ensuring that a string is a valid number (i.e., in range and containing no
-trailing characters) requires clearing
-.Va errno
-beforehand explicitly since
-.Va errno
-is not changed on a successful call to
-.Fn strtoul ,
-and the return value of
-.Fn strtoul
-cannot be used unambiguously to signal an error:
-.Bd -literal -offset indent
-char *ep;
-unsigned long ulval;
-
-\&...
-
-errno = 0;
-ulval = strtoul(buf, &ep, 10);
-if (buf[0] == '\e0' || *ep != '\e0')
-        goto not_a_number;
-if (errno == ERANGE && ulval == ULONG_MAX)
-        goto out_of_range;
-.Ed
-.Pp
-This example will accept
-.Dq 12
-but not
-.Dq 12foo
-or
-.Dq 12\en .
-If trailing whitespace is acceptable, further checks must be done on
-.Va *ep ;
-alternately, use
-.Xr sscanf 3 .
-.Sh ERRORS
-.Bl -tag -width Er
-.It Bq Er EINVAL
-The value of
-.Ar base
-was neither between 2 and 36 inclusive nor the special value 0.
-.It Bq Er ERANGE
-The given string was out of range; the value converted has been clamped.
-.El
-.Sh SEE ALSO
-.Xr sscanf 3 ,
-.Xr strtol 3
-.Sh STANDARDS
-The
-.Fn strtoul ,
-.Fn strtoull ,
-and
-.Fn strtoumax
-functions conform to
-.St -isoC-99 .
-Setting
-.Va errno
-to
-.Dv EINVAL
-is an extension to that standard required by
-.St -p1003.1-2008 .
-.Pp
-The
-.Fn strtouq
-function is a
-.Bx
-extension and is provided for backwards compatibility with legacy programs.
-.Sh BUGS
-Ignores the current locale.

-.Dt SYSTEM 3
-.Os
-.Sh NAME
-.Nm system
-.Nd pass a command to the shell
-.Sh SYNOPSIS
-.In stdlib.h
-.Ft int
-.Fn system "const char *string"
-.Sh DESCRIPTION
-The
-.Fn system
-function hands the argument
-.Fa string
-to the command interpreter
-.Xr sh 1 .
-The calling process waits for the shell to finish executing the command,
-ignoring
-.Dv SIGINT
-and
-.Dv SIGQUIT ,
-and blocking
-.Dv SIGCHLD .
-.Pp
-If
-.Fa string
-is
-.Dv NULL ,
-.Fn system
-will return non-zero.
-Otherwise,
-.Fn system
-returns the termination status of the shell in the format specified by
-.Xr waitpid 2 .
-.Pp
-Note that fork handlers established using
-.Xr pthread_atfork 3
-are not called when a multithreaded program calls
-.Fn system .
-.Sh RETURN VALUES
-If a child process cannot be created, or the termination status of
-the shell cannot be obtained,
-.Fn system
-returns \-1 and sets
-.Va errno
-to indicate the error.
-If execution of the shell fails,
-.Fn system
-returns the termination status for a program that terminates with a call of
-.Fn exit 127 .
-.Sh SEE ALSO
-.Xr sh 1 ,
-.Xr execve 2 ,
-.Xr waitpid 2 ,
-.Xr popen 3
-.Sh STANDARDS
-The
-.Fn system
-function conforms to
-.St -ansiC
-and
-.St -p1003.2-92 .
-.Sh HISTORY
-The
-.Fn system
-function first appeared in
-.At v6 .
-.Sh CAVEATS
-Never supply the
-.Fn system
-function with a command containing any part of an unsanitized user-supplied
-string.
-Shell meta-characters present will be honored by the
-.Xr sh 1
-command interpreter.
-.Pp
-It is often simpler to bypass the shell and run an external command using
-.Xr fork 2 ,
-.Xr execlp 3 ,
-and
-.Xr waitpid 2
-directly instead of having to sanitize a string for shell consumption.

-.Dt TSEARCH 3
-.Os
-.Sh NAME
-.Nm tsearch ,
-.Nm tfind ,
-.Nm tdelete ,
-.Nm twalk
-.Nd manipulate binary search trees
-.Sh SYNOPSIS
-.In search.h
-.Ft void *
-.Fn tdelete "const void *key" "void **rootp" "int (*compar)(const void *, const void *)"
-.Ft void *
-.Fn tfind "const void *key" "void * const *rootp" "int (*compar)(const void *, const void *)"
-.Ft void *
-.Fn tsearch "const void *key" "void **rootp" "int (*compar)(const void *, const void *)"
-.Ft void
-.Fn twalk "const void *root" "void (*action)(const void *, VISIT, int)"
-.Sh DESCRIPTION
-The
-.Fn tdelete ,
-.Fn tfind ,
-.Fn tsearch ,
-and
-.Fn twalk
-functions manage binary search trees based on algorithms T and D
-from Knuth (6.2.2).
-The comparison function passed in by
-the user has the same style of return values as
-.Xr strcmp 3 .
-.Pp
-.Fn tfind
-searches for the datum matched by the argument
-.Fa key
-in the binary tree rooted at
-.Fa rootp ,
-returning a pointer to the datum if it is found and
-.Dv NULL
-if it is not.
-.Pp
-.Fn tsearch
-is identical to
-.Fn tfind
-except that if no match is found,
-.Fa key
-is inserted into the tree and a pointer to it is returned.
-If
-.Fa rootp
-points to a null value a new binary search tree is created.
-.Pp
-.Fn tdelete
-deletes a node from the specified binary search tree and returns
-a pointer to the parent of the node to be deleted.
-If the node to be deleted is the root of the binary search tree,
-.Fa rootp
-will be adjusted and an unspecified non-null pointer will be returned.
-It takes the same arguments as
-.Fn tfind
-and
-.Fn tsearch .
-.Pp
-.Fn twalk
-walks the binary search tree rooted in
-.Fa root
-and calls the function
-.Fa action
-on each node.
-.Fa action
-is called with three arguments: a pointer to the current node,
-a value from the enum
-.Sy "typedef enum { preorder, postorder, endorder, leaf } VISIT;"
-specifying the traversal type, and a node level (where level
-zero is the root of the tree).
-.Sh RETURN VALUES
-The
-.Fn tsearch
-function returns
-.Dv NULL
-if allocation of a new node fails (usually
-due to a lack of free memory).
-.Pp
-.Fn tdelete
-returns a pointer to the parent of the deleted node or an unspecified
-non-null pointer if the root node is deleted.
-.Pp
-.Fn tfind ,
-.Fn tsearch ,
-and
-.Fn tdelete
-return
-.Dv NULL
-if
-.Fa rootp
-is
-.Dv NULL
-or the datum cannot be found.
-.Sh SEE ALSO
-.Xr bsearch 3 ,
-.Xr lsearch 3
-.Sh STANDARDS
-These functions conform to
-.St -p1003.1-2008 .
-.Sh CAVEATS
-The value returned when deleting the root node was unspecified before
-the
-.St -p1003.1-2008
-standard, so users of the
-.Fn tdelete
-function should be wary of relying on a specific behaviour.
