-.Dt STPCPY 3
-.Os
-.Sh NAME
-.Nm stpcpy ,
-.Nm stpncpy
-.Nd copy strings
-.Sh SYNOPSIS
-.In string.h
-.Ft char *
-.Fn stpcpy "char *dst" "const char *src"
-.Ft char *
-.Fn stpncpy "char *dst" "const char *src" "size_t len"
-.Sh DESCRIPTION
-The
-.Fn stpcpy
-and
-.Fn stpncpy
-functions copy the string
-.Fa src
-to
-.Fa dst
-(including the terminating
-.Ql \e0
-character).
-.Pp
-The
-.Fn stpncpy
-function copies not more than
-.Fa len
-characters into
-.Fa dst ,
-appending
-.Ql \e0
-characters if
-.Fa src
-is less than
-.Fa len
-characters long, and
-.Em not
-terminating
-.Fa dst
-if the length of
-.Fa src
-is greater than or equal to
-.Fa len .
-.Pp
-If the
-.Fa src
-and
-.Fa dst
-strings overlap, the behavior is undefined.
-.Sh RETURN VALUES
-The
-.Fn stpcpy
-function returns a pointer to the terminating
-.Ql \e0
-character written into
-.Fa dst .
-.Pp
-The
-.Fn stpncpy
-function returns a pointer to the first
-.Ql \e0
-character written into
-.Fa dst ,
-or to
-.Fa &dst[len]
-if the length of
-.Fa src
-is greater than or equal to
-.Fa len .
-.Sh EXAMPLES
-The most common use of
-.Fn stpcpy
-is to build up a string from multiple elements.
-The following example builds up a pathname from
-directory and file components using
-.Fn stpcpy :
-.Bd -literal -offset indent
-char *dir, *file, pname[PATH_MAX];
-\&...
-if (strlen(dir) + strlen("/") + strlen(file) >= sizeof(pname))
-        goto toolong;
-stpcpy(stpcpy(stpcpy(pname, dir), "/"), file);
-.Ed
-.Pp
-However, the size check required to avoid a buffer overflow is error
-prone since the check can become out of sync with the code that
-performs the copy.
-.Pp
-One might expect that
-.Fn stpncpy
-could be safely used instead, but it suffers from the same defects as
-.Fn strncpy .
-The example below using
-.Fn stpncpy
-is even more prone to error and will not detect when truncation occurs:
-.Bd -literal -offset indent
-char *dir, *file, pname[PATH_MAX];
-char *p1, *p2;
-\&...
-p1 = stpncpy(pname, dir, sizeof(pname) - 1);
-p2 = stpncpy(p1, "/", sizeof(pname) - 1 - (p1 - pname));
-stpncpy(p2, file, sizeof(pname) - 1 - (p2 - pname));
-pname[sizeof(pname) - 1] = '\e0';
-.Ed
-.Pp
-A safer (and simpler) approach is to use
-.Fn snprintf :
-.Bd -literal -offset indent
-char *dir, *file, pname[PATH_MAX];
-int len;
-\&...
-len = snprintf(pname, sizeof(pname), "%s/%s", dir, file);
-if (len >= sizeof(pname))
-        goto toolong;
-.Ed
-.Pp
-In most cases, it is better to use
-.Fn snprintf ,
-.Fn strlcpy ,
-or
-.Fn strlcat .
-.Sh SEE ALSO
-.Xr snprintf 3 ,
-.Xr strcpy 3 ,
-.Xr strlcpy 3 ,
-.Xr strncpy 3
-.Sh STANDARDS
-The
-.Fn stpcpy
-and
-.Fn stpncpy
-functions conform to
-.St -p1003.1-2008 .
-.Sh HISTORY
-The function
-.Fn stpcpy
-first appeared in the Lattice C AmigaDOS compiler (1986 or earlier).
-The function
-.Fn stpncpy
-first appeared in the GNU C library version 1.07 (1993).
-Both functions have been available since
-.Ox 5.1 .

-.Sh DESCRIPTION
-These functions compare the NUL-terminated strings
-.Fa s1
-and
-.Fa s2
-and return an integer greater than, equal to, or less than 0,
-according to whether
-.Fa s1
-is lexicographically greater than, equal to, or less than
-.Fa s2
-after translation of each corresponding character to lower-case.
-The strings themselves are not modified.
-The comparison is done using unsigned characters, so that
-.Sq Li \e200
-is greater than
-.Ql \e0 .
-.Pp
-.Fn strncasecmp
-and
-.Fn strncasecmp_l
-compare at most
-.Fa len
-characters.
-.Pp
-On
-.Ox ,
-these functions always use the C locale and ignore
-the global locale, the thread-specific locale, and the
-.Fa locale
-argument.
-.Sh ENVIRONMENT
-On other operating systems, the behaviour of
-.Fn strcasecmp
-and
-.Fn strncasecmp
-may depend on the
-.Dv LC_CTYPE
-.Xr locale 1 .

-.Dt STRDUP 3
-.Os
-.Sh NAME
-.Nm strdup ,
-.Nm strndup
-.Nd save a copy of a string
-.Sh SYNOPSIS
-.In string.h
-.Ft char *
-.Fn strdup "const char *s"
-.Ft char *
-.Fn strndup "const char *s" "size_t maxlen"
-.Sh DESCRIPTION
-The
-.Fn strdup
-function allocates sufficient memory for a copy of the string
-.Fa s ,
-does the copy, and returns a pointer to it.
-The pointer may subsequently be used as an argument to the function
-.Xr free 3 .
-.Pp
-The
-.Fn strndup
-function behaves similarly to
-.Nm strdup
-but only copies up to
-.Fa maxlen
-characters from
-.Fa s .
-The resulting string is always NUL-terminated.
-.Pp
-If the memory allocation fails,
-.Dv NULL
-is returned.
-.Sh EXAMPLES
-The following will point
-.Va p
-to an allocated area of memory containing the NUL-terminated string
-.Qq foobar :
-.Bd -literal -offset indent
-char *p;
-p = strdup("foobar");
-if (p == NULL)
-        err(1, NULL);
-.Ed
-.Sh ERRORS
-The
-.Fn strdup
-and
-.Fn strndup
-functions may fail and set the external variable
-.Va errno
-for any of the errors specified for the library function
-.Xr malloc 3 .
-.Sh SEE ALSO
-.Xr free 3 ,
-.Xr malloc 3 ,
-.Xr strcpy 3 ,
-.Xr strlcpy 3 ,
-.Xr strlen 3 ,
-.Xr wcsdup 3
-.Sh STANDARDS
-The
-.Fn strdup
-and
-.Fn strndup
-functions conform to
-.St -p1003.1-2008 .
-.Sh HISTORY
-A
-.Fn strdup
-macro was first used in the
-.Bx 4.1c
-debugger,
-.Sy dbx .
-It was rewritten as a C function for the
-.Bx 4.3
-.Xr inetd 8
-and first appeared in the C library of
-.Bx 4.3 Reno .
-The
-.Fn strndup
-function appeared in glibc 2.0, was reimplemented for
-.Nx 4.0 ,
-and ported to
-.Ox 4.8 .

-.Fn strerror_l "int errnum" "locale_t locale"
-.Ft int
-.Fn strerror_r "int errnum" "char *strerrbuf" "size_t buflen"
-.Sh DESCRIPTION
-These functions map the error number
-.Fa errnum
-to an error message string.
-.Pp
-.Fn strerror
-and
-.Fn strerror_l
-return a string containing a maximum of
-.Dv NL_TEXTMAX
-characters, including the trailing NUL.
-This string is not to be modified by the calling program.
-The string returned by
-.Fn strerror
-may be overwritten by subsequent calls to
-.Fn strerror
-in any thread.
-The string returned by
-.Fn strerror_l
-may be overwritten by subsequent calls to
-.Fn strerror_l
-in the same thread.
-.Pp
-.Fn strerror_r
-is a thread safe version of
-.Fn strerror
-that places the error message in the specified buffer
-.Fa strerrbuf .
-.Pp
-On
-.Ox ,
-the global locale, the thread-specific locale, and the
-.Fa locale
-argument are ignored.
-.Sh RETURN VALUES
-.Fn strerror
-and
-.Fn strerror_l
-return a pointer to the error message string.
-If an error occurs, the error code is stored in
-.Va errno .
-.Pp
-.Fn strerror_r
-returns zero upon successful completion.
-If an error occurs, the error code is stored in
-.Va errno
-and the error code is returned.
-.Sh ERRORS
-All these functions may fail if:
-.Bl -tag -width Er
-.It Bq Er EINVAL
-.Fa errnum
-is not a valid error number.
-The returned error string will consist of an error message that includes
-.Fa errnum .
-.El
-.Pp
-.Fn strerror_r
-may also fail if:
-.Bl -tag -width Er
-.It Bq Er ERANGE
-The error message is larger than
-.Fa buflen
-characters.
-The message will be truncated to fit.
-.El

-.Sh NAME
-.Nm strlcpy ,
-.Nm strlcat
-.Nd size-bounded string copying and concatenation
-.Sh SYNOPSIS
-.In string.h
-.Ft size_t
-.Fn strlcpy "char * restrict dst" "const char * restrict src" "size_t dstsize"
-.Ft size_t
-.Fn strlcat "char * restrict dst" "const char * restrict src" "size_t dstsize"
-.Sh DESCRIPTION
-The
-.Fn strlcpy
-and
-.Fn strlcat
-functions copy and concatenate strings with the
-same input parameters and output result as
-.Xr snprintf 3 .
-They are designed to be safer, more consistent, and less error
-prone replacements for the easily misused functions
-.Xr strncpy 3
-and
-.Xr strncat 3 .
-.Pp
-.Fn strlcpy
-and
-.Fn strlcat
-take the full size of the destination buffer and guarantee
-NUL-termination if there is room.
-Note that room for the NUL should be included in
-.Fa dstsize .
-.Pp
-.Fn strlcpy
-copies up to
-.Fa dstsize
-\- 1 characters from the string
-.Fa src
-to
-.Fa dst ,
-NUL-terminating the result if
-.Fa dstsize
-is not 0.
-.Pp
-.Fn strlcat
-appends string
-.Fa src
-to the end of
-.Fa dst .
-It will append at most
-.Fa dstsize
-\- strlen(dst) \- 1 characters.
-It will then NUL-terminate, unless
-.Fa dstsize
-is 0 or the original
-.Fa dst
-string was longer than
-.Fa dstsize
-(in practice this should not happen
-as it means that either
-.Fa dstsize
-is incorrect or that
-.Fa dst
-is not a proper string).
-.Pp
-If the
-.Fa src
-and
-.Fa dst
-strings overlap, the behavior is undefined.
-.Sh RETURN VALUES
-Besides quibbles over the return type
-.Pf ( Va size_t
-versus
-.Va int )
-and signal handler safety
-.Pf ( Xr snprintf 3
-is not entirely safe on some systems), the
-following two are equivalent:
-.Bd -literal -offset indent
-n = strlcpy(dst, src, len);
-n = snprintf(dst, len, "%s", src);
-.Ed
-.Pp
-Like
-.Xr snprintf 3 ,
-the
-.Fn strlcpy
-and
-.Fn strlcat
-functions return the total length of the string they tried to create.
-For
-.Fn strlcpy
-that means the length of
-.Fa src .
-For
-.Fn strlcat
-that means the initial length of
-.Fa dst
-plus
-the length of
-.Fa src .
-.Pp
-If the return value is
-.Cm >=
-.Va dstsize ,
-the output string has been truncated.
-It is the caller's responsibility to handle this.
-.Sh EXAMPLES
-The following code fragment illustrates the simple case:
-.Bd -literal -offset indent
-char *s, *p, buf[BUFSIZ];
-\&...
-(void)strlcpy(buf, s, sizeof(buf));
-(void)strlcat(buf, p, sizeof(buf));
-.Ed
-.Pp
-To detect truncation, perhaps while building a pathname, something
-like the following might be used:
-.Bd -literal -offset indent
-char *dir, *file, pname[PATH_MAX];
-\&...
-if (strlcpy(pname, dir, sizeof(pname)) >= sizeof(pname))
-        goto toolong;
-if (strlcat(pname, file, sizeof(pname)) >= sizeof(pname))
-        goto toolong;
-.Ed
-.Pp
-Since it is known how many characters were copied the first time, things
-can be sped up a bit by using a copy instead of an append:
-.Bd -literal -offset indent
-char *dir, *file, pname[PATH_MAX];
-size_t n;
-\&...
-n = strlcpy(pname, dir, sizeof(pname));
-if (n >= sizeof(pname))
-        goto toolong;
-if (strlcpy(pname + n, file, sizeof(pname) - n) >= sizeof(pname) - n)
-        goto toolong;
-.Ed
-.Pp
-However, one may question the validity of such optimizations, as they
-defeat the whole purpose of
-.Fn strlcpy
-and
-.Fn strlcat .
-As a matter of fact, the first version of this manual page got it wrong.

-.Dt STRMODE 3
-.Os
-.Sh NAME
-.Nm strmode
-.Nd convert inode status information into a symbolic string
-.Sh SYNOPSIS
-.In string.h
-.Ft void
-.Fn strmode "mode_t mode" "char *bp"
-.Sh DESCRIPTION
-The
-.Fn strmode
-function converts a file
-.Fa mode
-(the type and permission information associated with an inode, see
-.Xr stat 2 )
-into a symbolic string which is stored in the location referenced by
-.Fa bp .
-This stored string is eleven characters in length plus a trailing NUL byte.
-.Pp
-The first character is the inode type, and will be one of the following:
-.Pp
-.Bl -tag -width flag -offset indent -compact
-.It \-
-regular file
-.It b
-block special
-.It c
-character special
-.It d
-directory
-.It l
-symbolic link
-.It p
-FIFO
-.It s
-socket
-.It \&?
-unknown inode type
-.El
-.Pp
-The next nine characters encode three sets of permissions, in three
-characters each.
-The first three characters are the permissions for the owner of the
-file, the second three for the group the file belongs to, and the
-third for the
-.Dq other ,
-or default, set of users.
-.Pp
-Permission checking is done as specifically as possible.
-If read permission is denied to the owner of a file in the first set
-of permissions, the owner of the file will not be able to read the file.
-This is true even if the owner is in the file's group and the group
-permissions allow reading or the
-.Dq other
-permissions allow reading.
-.Pp
-If the first character of the three character set is an
-.Sq r ,
-the file is readable for that set of users; if a dash
-.Pq Ql - ,
-it is not readable.
-.Pp
-If the second character of the three character set is a
-.Sq w ,
-the file is writable for that set of users; if a dash
-.Pq Ql - ,
-it is not writable.
-.Pp
-The third character is the first of the following characters that apply:
-.Bl -tag -width xxxx
-.It S
-If the character is part of the owner permissions and the file is not
-executable or the directory is not searchable by the owner, and the
-set-user-ID bit is set.
-.It S
-If the character is part of the group permissions and the file is not
-executable or the directory is not searchable by the group, and the
-set-group-ID bit is set.
-.It T
-If the character is part of the other permissions and the file is not
-executable or the directory is not searchable by others, and the
-.Dq sticky
-.Pq Dv S_ISVTX
-bit is set.
-.It s
-If the character is part of the owner permissions and the file is
-executable or the directory searchable by the owner, and the set-user-ID
-bit is set.
-.It s
-If the character is part of the group permissions and the file is
-executable or the directory searchable by the group, and the set-group-ID
-bit is set.
-.It t
-If the character is part of the other permissions and the file is
-executable or the directory searchable by others, and the
-.Dq sticky
-.Pq Dv S_ISVTX
-bit is set.
-.It x
-The file is executable or the directory is searchable.
-.It \-
-None of the above apply.
-.El
-.Pp
-The last character is a plus sign
-.Pq Ql +
-if there are any alternate
-or additional access control methods associated with the inode, otherwise
-it will be a space.

-.Dd $Mdocdate: April 19 2014 $
-.Dt STRNCAT 3
-.Os
-.Sh NAME
-.Nm strncat
-.Nd concatenate a string with part of another
-.Sh SYNOPSIS
-.In string.h
-.Ft char *
-.Fn strncat "char *dst" "const char *append" "size_t count"
-.Sh DESCRIPTION
-The
-.Fn strncat
-function appends not more than
-.Fa count
-characters of the string
-.Fa append
-to the end of the string found in the buffer
-.Fa dst .
-Space for the terminating
-.Ql \e0
-should not be included in
-.Fa count .
-.Pp
-Bounds checking must be performed manually with great care.
-If the buffer
-.Fa dst
-is not large enough to hold the result,
-subsequent memory will be damaged.
-.Sh RETURN VALUES
-The
-.Fn strncat
-function returns the pointer
-.Fa dst .
-.Sh EXAMPLES
-The following example shows how to use
-.Fn strncat
-in conjunction with
-.Xr strncpy 3 :
-.Bd -literal -offset indent
-char buf[BUFSIZ];
-char *base, *suffix;
-(void)strncpy(buf, base, sizeof(buf) - 1);
-buf[sizeof(buf) - 1] = '\e0';
-(void)strncat(buf, suffix, sizeof(buf) - 1 - strlen(buf));
-.Ed
-.Pp
-The above will copy as many characters from
-.Va base
-to
-.Va buf
-as will fit.
-It then appends as many characters from
-.Va suffix
-as will fit.
-If either
-.Va base
-or
-.Va suffix
-are too large, truncation will occur without detection.
-.Pp
-The above example shows dangerous coding patterns, including an
-inability to detect truncation.
-.Fn strncat
-and
-.Fn strncpy
-are dangerously easy to misuse.
-The
-.Xr strlcpy 3
-and
-.Xr strlcat 3
-functions are safer for this kind of operation:
-.Bd -literal -offset indent
-if (strlcpy(buf, base, sizeof(buf)) >= sizeof(buf) ||
-    strlcat(buf, suffix, sizeof(buf)) >= sizeof(buf))
-        goto toolong;
-.Ed
-or for greatest portability,
-.Bd -literal -offset indent
-if (snprintf(buf, sizeof(buf), "%s%s",
-    base, suffix) >= sizeof(buf))
-        goto toolong;
-.Ed
-.Sh SEE ALSO
-.Xr strlcpy 3 ,
-.Xr wcscat 3 ,
-.Xr wcslcpy 3
-.Sh STANDARDS
-The
-.Fn strncat
-function conforms to
-.St -ansiC .
-.Sh HISTORY
-The
-.Fn strncat
-function first appeared in
-.At v7 .

-.Fa src
-to the buffer
-.Fa dst .
-If
-.Fa src

-.Os
-.Sh NAME
-.Nm strsep
-.Nd separate strings
-.Sh SYNOPSIS
-.In string.h
-.Ft char *
-.Fn strsep "char **stringp" "const char *delim"
-.Sh DESCRIPTION
-The
-.Fn strsep
-function locates, in the string referenced by
-.Fa *stringp ,
-the first occurrence of any character in the string
-.Fa delim
-(or the terminating
-.Ql \e0
-character) and replaces it with a
-.Ql \e0 .
-The location of the next character after the delimiter character
-(or
-.Dv NULL ,
-if the end of the string was reached) is stored in
-.Fa *stringp .
-The original value of
-.Fa *stringp
-is returned.
-.Pp
-An
-.Dq empty
-field, i.e., one caused by two adjacent delimiter characters,
-can be detected by comparing the location referenced by the pointer returned
-by
-.Fn strsep
-to
-.Ql \e0 .
-.Pp
-If
-.Fa *stringp
-is initially
-.Dv NULL ,
-.Fn strsep
-returns
-.Dv NULL .
-.Sh EXAMPLES
-The following uses
-.Fn strsep
-to parse a string, containing tokens delimited by whitespace, into an
-argument vector:
-.Bd -literal -offset indent
-char **ap, *argv[10], *inputstring;
-for (ap = argv; ap < &argv[9] &&
-    (*ap = strsep(&inputstring, " \et")) != NULL;) {
-        if (**ap != '\e0')
-                ap++;
-}
-*ap = NULL;
-.Ed
-.Sh HISTORY
-The
-.Fn strsep
-function first appeared in
-.Bx 4.3 Reno .
-It is intended as a replacement for the
-.Xr strtok 3
-function.
-While the
-.Xr strtok 3
-function should be preferred for portability reasons (it conforms to
-.St -ansiC )
-it is unable to handle empty fields, i.e., detect fields delimited by
-two adjacent delimiter characters, or to be used for more than a single
-string at a time.

-.Fa str .
-These tokens are separated in the string by at least one of the
-characters in
-.Fa sep .
-The first time that
-.Fn strtok
-is called,
-.Fa str
-should be specified; subsequent calls, wishing to obtain further tokens
-from the same string, should pass a null pointer instead.
-The separator string,
-.Fa sep ,
-must be supplied each time, and may change between calls.
-.Pp
-The
-.Fn strtok_r
-function is a version of
-.Fn strtok
-that takes an explicit context argument and is reentrant.
-.Pp
-Since
-.Fn strtok
-and
-.Fn strtok_r
-modify the string,
-.Fa str
-should not point to an area in the initialized data segment.
-.Sh RETURN VALUES
-The
-.Fn strtok
-and
-.Fn strtok_r
-functions return a pointer to the beginning of each subsequent token
-in the string, after replacing the separator character itself with
-a NUL character.
-When no more tokens remain, a null pointer is returned.
-.Sh EXAMPLES
-The following will construct an array of pointers to each individual word in
-the string
-.Va s :
-.Bd -literal -offset indent
-#define MAXTOKENS       128
-char s[512], *p, *tokens[MAXTOKENS];
-char *last;
-int i = 0;
-snprintf(s, sizeof(s), "cat dog horse cow");
-for ((p = strtok_r(s, " ", &last)); p;
-    (p = strtok_r(NULL, " ", &last))) {
-        if (i < MAXTOKENS - 1)
-                tokens[i++] = p;
-}
-tokens[i] = NULL;
-.Ed
-.Pp
-That is,
-.Li tokens[0]
-will point to
-.Qq cat ,
-.Li tokens[1]
-will point to
-.Qq dog ,
-.Li tokens[2]
-will point to
-.Qq horse ,
-and
-.Li tokens[3]
-will point to
-.Qq cow .

-.Sh STANDARDS
-The
-.Fn strtok
-function conforms to
-.St -ansiC .
-The
-.Fn strtok_r
-function conforms to
-.St -p1003.1-2001 .
-.Sh HISTORY
-The
-.Fn strtok
-function first appeared in
-.At III
-and was reimplemented for
-.Bx 4.3 .
-The
-.Fn strtok_r
-function first appeared in
-.Nx 1.3
-and was reimplemented for
-.Ox 2.7 .
-.Sh BUGS
-The System V
-.Fn strtok ,
-if handed a string containing only delimiter characters,
-will not alter the next starting point, so that a call to
-.Fn strtok
-with a different (or empty) delimiter string
-may return a non-null value.
-Since this implementation always alters the next starting point,
-such a sequence of calls would always return
-.Dv NULL .

-.Sh DESCRIPTION
-The idea of
-.Fn strxfrm
-and
-.Fn strxfrm_l
-is to
-.Dq un-localize
-a string: the functions transform

-.Ar dst ,
-such that
-.Xr strcmp 3
-on transformed strings returns what
-.Xr strcoll 3
-on the original untransformed strings would return.
-.Pp
-On
-.Ox ,
-both have the same effect as
-.Xr strlcpy 3 ,
-and the global locale, the thread-specific locale, and the
-.Fa locale
-argument are ignored.
-On other operating systems, the behaviour may depend on the
-.Dv LC_CTYPE
-and

-.Sh DESCRIPTION
-The
-.Fn wcscat
-and
-.Fn wcsncat
-functions append a copy of the wide string
-.Fa append
-to the end of the wide string
-.Fa s ,
-then add a terminating null wide character (L'\e0').
-The wide string

-.Sh DESCRIPTION
-The
-.Fn wcscpy
-and
-.Fn wcsncpy
-functions copy the wide string
-.Fa src
-to
-.Fa dst
-(including the terminating null wide character).
-.Pp
-The

-function copies not more than
-.Fa len
-wide characters to
-.Fa dst ,
-appending null wide characters if the length of
-.Fa src
-is less than

-.Dd $Mdocdate: August 7 2024 $
-.Dt WCSLCPY 3
-.Os
-.Sh NAME
-.Nm wcslcpy ,
-.Nm wcslcat
-.Nd size-bounded wide string copying and concatenation
-.Sh SYNOPSIS
-.In wchar.h
-.Ft size_t
-.Fn wcslcpy "wchar_t * restrict dst" "const wchar_t * restrict src" "size_t size"
-.Ft size_t
-.Fn wcslcat "wchar_t * restrict dst" "const wchar_t * restrict src" "size_t size"
-.Sh DESCRIPTION
-The
-.Fn wcslcpy
-and
-.Fn wcslcat
-functions copy and concatenate wide strings respectively.
-They are designed to be safer, more consistent, and less error prone
-replacements for
-.Xr wcsncpy 3
-and
-.Xr wcsncat 3 .
-Unlike those functions,
-.Fn wcslcpy
-and
-.Fn wcslcat
-take the full size of the buffer (not just the length) and guarantee to
-terminate the result with a null wide character (as long as
-.Fa size
-is larger than 0 or, in the case of
-.Fn wcslcat ,
-as long as there is at least one wide character free in
-.Fa dst ) .
-Note that a wide character for the null wide character should be included in
-.Fa size .
-Also note that
-.Fn wcslcpy
-and
-.Fn wcslcat
-only operate on wide strings that are terminated with a null wide character
-(L'\e0').
-This means that for
-.Fn wcslcpy
-.Fa src
-must be terminated with a null wide character and for
-.Fn wcslcat
-both
-.Fa src
-and
-.Fa dst
-must be terminated with a null wide character.
-.Pp
-The
-.Fn wcslcpy
-function copies up to
-.Fa size
-\(mi 1 wide characters from the wide string
-.Fa src
-to
-.Fa dst ,
-terminating the result with a null wide character.
-.Pp
-The
-.Fn wcslcat
-function appends the wide string
-.Fa src
-to the end of
-.Fa dst .
-It will append at most
-.Fa size
-\(mi wcslen(dst) \(mi 1 wide characters, terminating the result with a null
-wide character.
-.Pp
-If the
-.Fa src
-and
-.Fa dst
-strings overlap, the behavior is undefined.
-.Sh RETURN VALUES
-The
-.Fn wcslcpy
-and
-.Fn wcslcat
-functions return the total length of the wide string they tried to create.
-For
-.Fn wcslcpy
-that means the length of
-.Fa src .
-For
-.Fn wcslcat
-that means the initial length of
-.Fa dst
-plus
-the length of
-.Fa src .
-While this may seem somewhat confusing, it was done to make
-truncation detection simple.
-.Pp
-Note, however, that if
-.Fn wcslcat
-traverses
-.Fa size
-wide characters without finding a null wide character, the length of the
-string is considered to be
-.Fa size
-and the destination wide string will not be terminated with a null wide
-character (since there was no space for it).
-This keeps
-.Fn wcslcat
-from running off the end of a wide string.
-In practice this should not happen (as it means that either
-.Fa size
-is incorrect or that
-.Fa dst
-is not terminated with a null wide character).
-The check exists to prevent potential security problems in incorrect code.
-.Sh SEE ALSO
-.Xr strlcpy 3 ,
-.Xr swprintf 3 ,
-.Xr wcsncat 3 ,
-.Xr wcsncpy 3
-.Sh STANDARDS
-The
-.Fn wcslcpy
-and
-.Fn wcslcat
-functions conform to
-.St -p1003.1-2024 .
-.Sh HISTORY
-The
-.Fn wcslcpy
-and
-.Fn wcslcat
-functions first appeared in
-.Ox 3.8 .
-.Sh AUTHORS
-The
-.Fn wcslcpy
-and
-.Fn wcslcat
-functions are based on code by
-.An Todd C. Miller Aq Mt millert@openbsd.org .

-.Dd $Mdocdate: July 25 2011 $
-.Dt WCSTOK 3
-.Os
-.Sh NAME
-.Nm wcstok
-.Nd split wide-character string into tokens
-.Sh SYNOPSIS
-.In wchar.h
-.Ft wchar_t *
-.Fn wcstok "wchar_t * restrict str" "const wchar_t * restrict sep" "wchar_t ** restrict last"
-.Sh DESCRIPTION
-The
-.Fn wcstok
-function
-is used to isolate sequential tokens in a NUL-terminated wide-character
-string,
-.Fa str .
-These tokens are separated in the string by at least one of the
-characters in
-.Fa sep .
-The first time that
-.Fn wcstok
-is called,
-.Fa str
-should be specified; subsequent calls, wishing to obtain further tokens
-from the same string, should pass a null pointer instead.
-The separator string,
-.Fa sep ,
-must be supplied each time, and may change between calls.
-The context pointer
-.Fa last
-must be provided on each call.
-.Pp
-The
-.Fn wcstok
-function is the wide-character counterpart of the
-.Xr strtok_r 3
-function.
-.Pp
-Since
-.Fn wcstok
-modifies the string,
-.Fa str
-should not point to an area in the initialized data segment.
-.Sh RETURN VALUES
-The
-.Fn wcstok
-function
-returns a pointer to the beginning of each subsequent token in the string,
-after replacing the token itself with a NUL wide character (L'\e0').
-When no more tokens remain, a null pointer is returned.
-.Sh EXAMPLES
-The following code fragment splits a wide-character string on
-.Tn ASCII
-space, tab, and newline characters and writes the tokens to
-standard output:
-.Bd -literal -offset indent
-const wchar_t *seps = L" \et\en";
-wchar_t *last, *tok, text[] = L" \enone\ettwo\et\etthree  \en";
-for (tok = wcstok(text, seps, &last); tok != NULL;
-    tok = wcstok(NULL, seps, &last))
-        wprintf(L"%ls\en", tok);
-.Ed

-.Xr wcschr 3 ,
-.Xr wcscspn 3 ,
-.Xr wcspbrk 3 ,
-.Xr wcsrchr 3 ,
-.Xr wcsspn 3 ,
-.Xr wcsstr 3 ,
-.Xr wmemchr 3
-.Sh STANDARDS
-The
-.Fn wcstok
-function
-conforms to
-.St -isoC-99 .
-.Sh HISTORY
-The
-.Fn wcstok
-function was ported from
-.Nx
-and first appeared in
-.Ox 3.8 .
-.Pp
-Some early implementations of
-.Fn wcstok
-omit the
-context pointer argument,
-.Fa last ,
-and maintain state across calls in a static variable like
-.Xr strtok 3
-does.
