41.Sh SYNOPSIS
42.Fd #include <sys/types.h>

44.Ft bm_pat *
45.Fn bm_comp "const unsigned char *pattern" "size_t patlen" \

48.Fn bm_exec "bm_pat *pdesc" "unsigned char *text" "size_t len"
49.Ft void
50.Fn bm_free "bm_pat *pdesc"
51.Sh DESCRIPTION
52These routines implement an efficient mechanism to find an
53occurrence of a byte string within another byte string.
54.Pp
55.Fn bm_comp
56evaluates
57.Fa patlen
58bytes starting at
59.Fa pattern
60and returns a pointer to a structure describing them.
61The bytes referenced by
62.Fa pattern
63may be of any value.
64.Pp
65The search takes advantage of the frequency distribution of the
66bytes in the text to be searched.
67If specified,
68.Ar freq
69should be an array of 256 values,
70with higher values indicating that the corresponding character occurs
71more frequently.
72(A less than optimal frequency distribution can only result in less
73than optimal performance, not incorrect results.)
74If
75.Ar freq
76is
77.Dv NULL ,
78a system default table is used.
79.Pp
80.Fn bm_exec
81returns a pointer to the leftmost occurrence of the string given to
82.Fn bm_comp
83within
84.Ar text ,
85or
86.Dv NULL
87if none occurs.
88The number of bytes in
89.Ar text
90must be specified by
91.Ar len .
92.Pp
93Space allocated for the returned description is discarded
94by calling
95.Fn bm_free
96with the returned description as an argument.
97.Pp
98The asymptotic speed of
99.Fn bm_exec
100is
101.Pf O Ns Pq len / patlen .

51Both strings are assumed to be
52.Fa len
53bytes long.
54.Sh RETURN VALUES
55The

57function returns zero if the two strings are identical,
58otherwise returns the difference between the first two differing bytes
59(treated as
60.Li unsigned char
61values, so that
62.Sq Li \e200
63is greater than
64.Sq Li \&\e0 ,
65for example).
66Zero-length strings are always identical.

70In this implementation
71.Fn memcpy
72is implemented using

74and therefore the buffers may overlap.
75On other systems, copying overlapping buffers may produce surprises.
76A simpler solution is to not use

38.Nm strcasecmp ,
39.Nm strncasecmp
40.Nd compare strings, ignoring case
41.Sh SYNOPSIS
42.Fd #include <string.h>
43.Ft int
44.Fn strcasecmp "const char *s1" "const char *s2"
45.Ft int
46.Fn strncasecmp "const char *s1" "const char *s2" "size_t len"
47.Sh DESCRIPTION
48The
49.Fn strcasecmp
50and
51.Fn strncasecmp
52functions compare the NUL-terminated strings
53.Fa s1
54and
55.Fa s2
56and return an integer greater than, equal to, or less than 0,
57according to whether
58.Fa s1
59is lexicographically greater than, equal to, or less than
60.Fa s2
61after translation of each corresponding character to lower-case.
62The strings themselves are not modified.
63The comparison is done using unsigned characters, so that
64.Sq Li \e200
65is greater than
66.Ql \e0 .
67.Pp
68.Fn strncasecmp
69compares at most
70.Fa len
71characters.

41.Sh SYNOPSIS
42.Fd #include <string.h>
43.Ft char *
44.Fn strcat "char *s" "const char *append"
45.Ft char *
46.Fn strncat "char *s" "const char *append" "size_t count"
47.Sh DESCRIPTION
48The
49.Fn strcat
50and
51.Fn strncat
52functions append a copy of the NUL-terminated string
53.Fa append
54to the end of the NUL-terminated string
55.Fa s ,
56then add a terminating
57.Ql \e0 .
58The string
59.Fa s
60must have sufficient space to hold the result.
61.Pp
62The
63.Fn strncat
64function appends not more than
65.Fa count
66characters where space for the terminating
67.Ql \e0
68should not be included in
69.Fa count .
70.Sh RETURN VALUES
71The
72.Fn strcat
73and
74.Fn strncat
75functions return the pointer
76.Fa s .
77.Sh EXAMPLES
78The following appends
79.Dq Li abc
80to
81.Va chararray :
82.Bd -literal -offset indent
83char *letters = "abcdefghi";
84
85(void)strncat(chararray, letters, 3);
86.Ed
87.Pp
88The following example shows how to use
89.Fn strncat
90safely in conjunction with
91.Xr strncpy 3 .
92.Bd -literal -offset indent
93char buf[BUFSIZ];
94char *input, *suffix;
95
96(void)strncpy(buf, input, sizeof(buf) - 1);
97buf[sizeof(buf) - 1] = '\e0';
98(void)strncat(buf, suffix, sizeof(buf) - 1 - strlen(buf));
99.Ed
100.Pp
101The above will copy as many characters from
102.Va input
103to
104.Va buf
105as will fit.
106It then appends as many characters from
107.Va suffix
108as will fit (or none
109if there is no space).
110For operations like this, the
111.Xr strlcpy 3
112and
113.Xr strlcat 3
114functions are a better choice, as shown below.
115.Bd -literal -offset indent
116(void)strlcpy(buf, input, sizeof(buf));
117(void)strlcat(buf, suffix, sizeof(buf));
118.Ed

87The following sets

98.Dq abcdef
99and does
100.Em not
101NUL terminate
102.Va chararray
103because the length of the source string is greater than or equal to the
104length parameter.
105.Fn strncpy
106.Em only
107NUL terminates the destination string when the length of the source
108string is less than the length parameter.
109.Bd -literal -offset indent
110(void)strncpy(chararray, "abcdefgh", 6);
111.Ed
112.Pp
113The following copies as many characters from
114.Va input
115to
116.Va buf
117as will fit and NUL terminates the result.
118Because
119.Fn strncpy
120does
121.Em not
122guarantee to NUL terminate the string itself, it must be done by hand.

128.Ed
129.Pp
130Note that
131.Xr strlcpy 3
132is a better choice for this kind of operation.
133The equivalent using

46.Sh DESCRIPTION
47The
48.Fn strerror
49and
50.Fn strerror_r
51functions map the error number
52.Fa errnum
53to a language-dependent error message string.
54.Pp
55.Fn strerror
56returns a string containing a maximum of
57.Dv NL_TEXTMAX
58characters, including the trailing NUL.
59This string is not to be modified by the calling program,
60but may be overwritten by subsequent calls to
61.Fn strerror .
62.Pp
63.Fn strerror_r
64is a thread safe version of
65.Fn strerror
66that places the error message in the specified buffer
67.Fa strerrbuf .
68.Sh RETURN VALUES
69.Fn strerror
70returns a pointer to the error message string.
71If an error occurs, the error code is stored in
72.Va errno .
73.Pp
74.Fn strerror_r
75returns zero upon successful completion.
76If an error occurs, the error code is stored in
77.Va errno
78and the error code is returned.
79.Sh ERRORS
80.Fn strerror
81and
82.Fn strerror_r
83may fail if:
84.Bl -tag -width Er
85.It Bq Er EINVAL
86.Fa errnum
87is not a valid error number.
88The returned error string will consist of an error message that includes
89.Fa errnum .
90.El
91.Pp
92.Fn strerror_r
93may fail if:
94.Bl -tag -width Er
95.It Bq Er ERANGE
96The error message is larger than
97.Fa buflen
98characters.
99The message will be truncated to fit.

85The string functions
86manipulate strings terminated by a
87NUL byte.
88.Pp
89See the specific manual pages for more information.
90For manipulating variable length generic objects as byte
91strings (without the NUL-byte check), see
92.Xr bstring 3 .
93.Pp
94Except as noted in their specific manual pages,
95the string functions do not test the destination
96for size limitations.

20.Sh NAME
21.Nm strlcpy ,
22.Nm strlcat
23.Nd size-bounded string copying and concatenation
24.Sh SYNOPSIS
25.Fd #include <string.h>
26.Ft size_t
27.Fn strlcpy "char *dst" "const char *src" "size_t size"
28.Ft size_t
29.Fn strlcat "char *dst" "const char *src" "size_t size"
30.Sh DESCRIPTION
31The
32.Fn strlcpy
33and
34.Fn strlcat
35functions copy and concatenate strings respectively.
36They are designed
37to be safer, more consistent, and less error prone replacements for
38.Xr strncpy 3
39and
40.Xr strncat 3 .
41Unlike those functions,
42.Fn strlcpy
43and
44.Fn strlcat
45take the full size of the buffer (not just the length) and guarantee to
46NUL-terminate the result (as long as
47.Fa size
48is larger than 0 or, in the case of
49.Fn strlcat ,
50as long as there is at least one byte free in
51.Fa dst ) .
52Note that a byte for the NUL should be included in
53.Fa size .
54Also note that
55.Fn strlcpy
56and
57.Fn strlcat
58only operate on true
59.Dq C
60strings.
61This means that for
62.Fn strlcpy
63.Fa src
64must be NUL-terminated and for
65.Fn strlcat
66both
67.Fa src
68and
69.Fa dst
70must be NUL-terminated.
71.Pp
72The
73.Fn strlcpy
74function copies up to
75.Fa size
76- 1 characters from the NUL-terminated string
77.Fa src
78to
79.Fa dst ,
80NUL-terminating the result.
81.Pp
82The
83.Fn strlcat
84function appends the NUL-terminated string
85.Fa src
86to the end of
87.Fa dst .
88It will append at most
89.Fa size
90- strlen(dst) - 1 bytes, NUL-terminating the result.
91.Sh RETURN VALUES
92The
93.Fn strlcpy
94and
95.Fn strlcat
96functions return the total length of the string they tried to create.
97For
98.Fn strlcpy
99that means the length of
100.Fa src .
101For
102.Fn strlcat
103that means the initial length of
104.Fa dst
105plus
106the length of
107.Fa src .
108While this may seem somewhat confusing, it was done to make
109truncation detection simple.
110.Pp
111Note, however, that if
112.Fn strlcat
113traverses
114.Fa size
115characters without finding a NUL, the length of the string is considered
116to be
117.Fa size
118and the destination string will not be NUL-terminated (since there was
119no space for the NUL).
120This keeps
121.Fn strlcat
122from running off the end of a string.
123In practice this should not happen (as it means that either
124.Fa size
125is incorrect or that
126.Fa dst
127is not a proper
128.Dq C
129string).
130The check exists to prevent potential security problems in incorrect code.
131.Sh EXAMPLES
132The following code fragment illustrates the simple case:
133.Bd -literal -offset indent
134char *s, *p, buf[BUFSIZ];
135
136\&...
137
138(void)strlcpy(buf, s, sizeof(buf));
139(void)strlcat(buf, p, sizeof(buf));
140.Ed
141.Pp
142To detect truncation, perhaps while building a pathname, something
143like the following might be used:
144.Bd -literal -offset indent
145char *dir, *file, pname[MAXPATHLEN];
146
147\&...
148
149if (strlcpy(pname, dir, sizeof(pname)) >= sizeof(pname))
150 goto toolong;
151if (strlcat(pname, file, sizeof(pname)) >= sizeof(pname))
152 goto toolong;
153.Ed
154.Pp
155Since it is known how many characters were copied the first time, things
156can be sped up a bit by using a copy instead of an append:
157.Bd -literal -offset indent
158char *dir, *file, pname[MAXPATHLEN];
159size_t n;
160
161\&...
162
163n = strlcpy(pname, dir, sizeof(pname));
164if (n >= sizeof(pname))
165 goto toolong;
166if (strlcpy(pname + n, file, sizeof(pname) - n) >= sizeof(pname) - n)
167 goto toolong;
168.Ed
169.Pp
170However, one may question the validity of such optimizations, as they
171defeat the whole purpose of
172.Fn strlcpy
173and
174.Fn strlcat .
175As a matter of fact, the first version of this manual page got it wrong.

33.Dt STRMODE 3
34.Os
35.Sh NAME
36.Nm strmode
37.Nd convert inode status information into a symbolic string
38.Sh SYNOPSIS
39.Fd #include <string.h>
40.Ft void
41.Fn strmode "mode_t mode" "char *bp"
42.Sh DESCRIPTION
43The
44.Fn strmode
45function converts a file
46.Fa mode
47(the type and permission information associated with an inode, see
48.Xr stat 2 )
49into a symbolic string which is stored in the location referenced by
50.Fa bp .
51This stored string is eleven characters in length plus a trailing NUL byte.
52.Pp
53The first character is the inode type, and will be one of the following:
54.Pp
55.Bl -tag -width flag -offset indent -compact
56.It \-
57regular file
58.It b
59block special
60.It c
61character special
62.It d
63directory
64.It l
65symbolic link
66.It p
67FIFO
68.It s
69socket
70.It \&?
71unknown inode type
72.El
73.Pp
74The next nine characters encode three sets of permissions, in three
75characters each.
76The first three characters are the permissions for the owner of the
77file, the second three for the group the file belongs to, and the
78third for the
79.Dq other ,
80or default, set of users.
81.Pp
82Permission checking is done as specifically as possible.
83If read permission is denied to the owner of a file in the first set
84of permissions, the owner of the file will not be able to read the file.
85This is true even if the owner is in the file's group and the group
86permissions allow reading or the
87.Dq other
88permissions allow reading.
89.Pp
90If the first character of the three character set is an
91.Sq r ,
92the file is readable for that set of users; if a dash
93.Pq Ql - ,
94it is not readable.
95.Pp
96If the second character of the three character set is a
97.Sq w ,
98the file is writable for that set of users; if a dash
99.Pq Ql - ,
100it is not writable.
101.Pp
102The third character is the first of the following characters that apply:
103.Bl -tag -width xxxx
104.It S
105If the character is part of the owner permissions and the file is not
106executable or the directory is not searchable by the owner, and the
107set-user-ID bit is set.
108.It S
109If the character is part of the group permissions and the file is not
110executable or the directory is not searchable by the group, and the
111set-group-ID bit is set.
112.It T
113If the character is part of the other permissions and the file is not
114executable or the directory is not searchable by others, and the
115.Dq sticky
116.Pq Dv S_ISVTX
117bit is set.
118.It s
119If the character is part of the owner permissions and the file is
120executable or the directory searchable by the owner, and the set-user-ID
121bit is set.
122.It s
123If the character is part of the group permissions and the file is
124executable or the directory searchable by the group, and the set-group-ID
125bit is set.
126.It t
127If the character is part of the other permissions and the file is

36.Dt STRSEP 3
37.Os
38.Sh NAME
39.Nm strsep
40.Nd separate strings
41.Sh SYNOPSIS
42.Fd #include <string.h>
43.Ft char *
44.Fn strsep "char **stringp" "const char *delim"
45.Sh DESCRIPTION
46The
47.Fn strsep
48function locates, in the string referenced by
49.Fa *stringp ,
50the first occurrence of any character in the string
51.Fa delim
52(or the terminating
53.Ql \e0
54character) and replaces it with a
55.Ql \e0 .
56The location of the next character after the delimiter character
57(or
58.Dv NULL ,
59if the end of the string was reached) is stored in
60.Fa *stringp .
61The original value of
62.Fa *stringp
63is returned.
64.Pp
65An
66.Dq empty
67field, i.e., one caused by two adjacent delimiter characters,
68can be detected by comparing the location referenced by the pointer returned
69by
70.Fn strsep
71to
72.Ql \e0 .
73.Pp
74If
75.Fa *stringp
76is initially
77.Dv NULL ,
78.Fn strsep
79returns
80.Dv NULL .
81.Sh EXAMPLES
82The following uses
83.Fn strsep
84to parse a string, containing tokens delimited by whitespace, into an
85argument vector:
86.Bd -literal -offset indent
87char **ap, *argv[10], *inputstring;
88
89for (ap = argv; ap < &argv[9] &&
90 (*ap = strsep(&inputstring, " \et")) != NULL;) {
91 if (**ap != '\e0')
92 ap++;
93}
94*ap = NULL;
95.Ed
96.Sh HISTORY
97The
98.Fn strsep
99function is intended as a replacement for the
100.Fn strtok
101function.
102While the
103.Fn strtok
104function should be preferred for portability reasons (it conforms to
105.St -ansiC )
106it is unable to handle empty fields, i.e., detect fields delimited by
107two adjacent delimiter characters, or to be used for more than a single
108string at a time.
109The
110.Fn strsep
111function first appeared in
112.Bx 4.4 .

36.Os
37.Sh NAME
38.Nm strtok ,
39.Nm strtok_r
40.Nd string token operations
41.Sh SYNOPSIS
42.Fd #include <string.h>
43.Ft char *
44.Fn strtok "char *str" "const char *sep"
45.Ft char *
46.Fn strtok_r "char *str" "const char *sep" "char **last"
47.Sh DESCRIPTION
48.Bf -symbolic
49This interface is obsoleted by
50.Xr strsep 3 .
51.Ef
52.Pp
53The
54.Fn strtok
55function is used to isolate sequential tokens in a NUL-terminated string,
56.Fa str .
57These tokens are separated in the string by at least one of the
58characters in
59.Fa sep .
60The first time that
61.Fn strtok
62is called,
63.Fa str
64should be specified; subsequent calls, wishing to obtain further tokens
65from the same string, should pass a null pointer instead.
66The separator string,
67.Fa sep ,
68must be supplied each time, and may change between calls.
69.Pp
70The
71.Fn strtok_r
72function is a version of
73.Fn strtok
74that takes an explicit context argument and is reentrant.
75.Pp
76The
77.Fn strtok
78and
79.Fn strtok_r
80functions return a pointer to the beginning of each subsequent token
81in the string, after replacing the separator character itself with an
82.Tn ASCII NUL
83character.
84When no more tokens remain, a null pointer is returned.
85.Pp
86Since
87.Fn strtok
88and
89.Fn strtok_r
90modify the string,
91.Fa str
92should not point to an area in the initialized data segment.
93.Sh EXAMPLES
94The following will construct an array of pointers to each individual word in
95the string
96.Va s :
97.Bd -literal -offset indent
98#define MAXTOKENS 128
99
100char s[512], *p, *tokens[MAXTOKENS];
101char *last;
102int i = 0;
103
104snprintf(s, sizeof(s), "cat dog horse cow");
105
106for ((p = strtok_r(s, " ", &last)); p;
107 (p = strtok_r(NULL, " ", &last))) {
108 if (i < MAXTOKENS - 1)
109 tokens[i++] = p;
110}
111tokens[i] = NULL;
112.Ed
113.Pp
114That is,
115.Li tokens[0]
116will point to
117.Qq cat ,
118.Li tokens[1]
119will point to
120.Qq dog ,
121.Li tokens[2]
122will point to
123.Qq horse ,
124and
125.Li tokens[3]
126will point to
127.Qq cow .
128.Sh SEE ALSO
129.Xr memchr 3 ,
130.Xr strchr 3 ,
131.Xr strcspn 3 ,
132.Xr strpbrk 3 ,
133.Xr strrchr 3 ,
134.Xr strsep 3 ,
135.Xr strspn 3 ,
136.Xr strstr 3
137.Sh STANDARDS
138The
139.Fn strtok
140function conforms to
141.St -ansiC .
142.Sh BUGS
143The System V
144.Fn strtok ,
145if handed a string containing only delimiter characters,
146will not alter the next starting point, so that a call to
147.Fn strtok
148with a different (or empty) delimiter string
149may return a non-null value.
150Since this implementation always alters the next starting point,
151such a sequence of calls would always return
152.Dv NULL .

58.Dt WCSTOK 3
59.Os
60.Sh NAME
61.Nm wcstok
62.Nd split wide-character string into tokens
63.Sh SYNOPSIS
64.In wchar.h
65.Ft wchar_t *
66.Fn wcstok "wchar_t * restrict str" "const wchar_t * restrict sep" "wchar_t ** restrict last"
67.Sh DESCRIPTION
68The
69.Fn wcstok
70function
71is used to isolate sequential tokens in a NUL-terminated wide character
72string,
73.Fa str .
74These tokens are separated in the string by at least one of the
75characters in
76.Fa sep .
77The first time that
78.Fn wcstok
79is called,
80.Fa str
81should be specified; subsequent calls, wishing to obtain further tokens
82from the same string, should pass a null pointer instead.
83The separator string,
84.Fa sep ,
85must be supplied each time, and may change between calls.
86The context pointer
87.Fa last
88must be provided on each call.
89.Pp
90The
91.Fn wcstok
92function is the wide character counterpart of the
93.Fn strtok_r
94function.
95.Sh RETURN VALUES
96The
97.Fn wcstok
98function
99returns a pointer to the beginning of each subsequent token in the string,
100after replacing the token itself with a NUL wide character (L'\e0').
101When no more tokens remain, a null pointer is returned.
102.Sh EXAMPLES
103The following code fragment splits a wide character string on
104.Tn ASCII
105space, tab, and newline characters and writes the tokens to
106standard output:
107.Bd -literal -offset indent
108const wchar_t *seps = L" \et\en";
109wchar_t *last, *tok, text[] = L" \enone\ettwo\et\etthree \en";
110
111for (tok = wcstok(text, seps, &last); tok != NULL;
112 tok = wcstok(NULL, seps, &last))
113 wprintf(L"%ls\en", tok);
114.Ed
115.Sh SEE ALSO
116.Xr strtok 3 ,
117.Xr wcschr 3 ,
118.Xr wcscspn 3 ,
119.Xr wcspbrk 3 ,
120.Xr wcsrchr 3 ,
121.Xr wcsspn 3
122.Sh STANDARDS
123The
124.Fn wcstok
125function
126conforms to
127.St -isoC-99 .
128.Sh HISTORY
129Some early implementations of
130.Fn wcstok
131omit the
132context pointer argument,
133.Fa last ,
134and maintain state across calls in a static variable like
135.Fn strtok
136does.
