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

47.Sh DESCRIPTION
48The
49.Fn strcasecmp
50and
51.Fn strncasecmp
52functions compare the null-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

37.Sh NAME
38.Nm strcat ,
39.Nm strncat
40.Nd concatenate strings
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 null-terminated string
53.Fa append
54to the end of the null-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.Dq Li 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.Dq Li input
103to
104.Dq Li buf
105as will fit.
106It then appends as many characters from suffix as will fit (or none
107if there is no space).
108For operations like this, the
109.Xr strlcpy 3
110and
111.Xr strlcat 3
112functions are a better choice, as shown below.
113.Bd -literal -offset indent
114(void)strlcpy(buf, input, sizeof(buf));
115(void)strlcat(buf, suffix, sizeof(buf));

104.Fn strncpy

111.Pp
112The following copies as many characters from
113.Va input
114to
115.Va buf
116as will fit and null terminates the result.
117Because
118.Fn strncpy
119does
120.Em not
121guarantee to null terminate the string itself, we must do this by hand.

109.Pp
110See the specific manual pages for more information.
111For manipulating variable length generic objects as byte
112strings (without the null byte check), see
113.Xr bstring 3 .
114.Pp

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 you should include a byte for the NUL 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 we know how many characters we copied the first time, we can
156speed things 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.

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 null 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

64.It l
65symbolic link
66.It p
67FIFO
68.It s
69socket
70.It w
71whiteout
72.It \&?
73unknown inode type
74.El
75.Pp
76The next nine characters encode three sets of permissions, in three
77characters each.
78The first three characters are the permissions for the owner of the
79file, the second three for the group the file belongs to, and the
80third for the
81.Dq other ,
82or default, set of users.
83.Pp
84Permission checking is done as specifically as possible.
85If read permission is denied to the owner of a file in the first set
86of permissions, the owner of the file will not be able to read the file.
87This is true even if the owner is in the file's group and the group
88permissions allow reading or the
89.Dq other
90permissions allow reading.
91.Pp
92If the first character of the three character set is an
93.Sq r ,
94the file is readable for that set of users; if a dash
95.Pq Ql - ,
96it is not readable.
97.Pp
98If the second character of the three character set is a
99.Sq w ,
100the file is writable for that set of users; if a dash
101.Pq Ql - ,
102it is not writable.
103.Pp
104The third character is the first of the following characters that apply:
105.Bl -tag -width xxxx
106.It S
107If the character is part of the owner permissions and the file is not
108executable or the directory is not searchable by the owner, and the
109set-user-ID bit is set.
110.It S
111If the character is part of the group permissions and the file is not
112executable or the directory is not searchable by the group, and the
113set-group-ID bit is set.
114.It T
115If the character is part of the other permissions and the file is not
116executable or the directory is not searchable by others, and the
117.Dq sticky
118.Pq Dv S_ISVTX
119bit is set.
120.It s
121If the character is part of the owner permissions and the file is
122executable or the directory searchable by the owner, and the set-user-ID

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 .

35.Dt STRTOK 3
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 null-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)), i++) {
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 .
