57.SH DESCRIPTION
58These routines implement an efficient mechanism to find an
59occurrence of a byte string within another byte string.
60.PP
61.I Bm_comp
62evaluates the
63.I patlen
64bytes starting at
65.IR pattern ,
66and returns a pointer to a structure describing them.
67The bytes referenced by
68.I pattern
69may be of any value.
70.PP
71The search takes advantage of the frequency distribution of the
72bytes in the text to be searched.
73If specified,
74.I freq
75should be an array of 256 values,
76with higher values indicating that the corresponding character occurs
77more frequently.
78(A less than optimal frequency distribution can only result in less
79than optimal performance, not incorrect results.)
80If
81.I freq
82is NULL,
83a system default table is used.
84.PP
85.I Bm_exec
86returns a pointer to the leftmost occurrence of the string given to
87.I bm_comp
88within
89.IR text ,
90or NULL if none occurs.
91The number of bytes in
92.I text
93must be specified by
94.IR len .
95.PP
96Space allocated for the returned description is discarded
97by calling
98.I bm_free
99with the returned description as an argument.
100.PP
101The asymptotic speed of
102.I bm_exec
103is
104.RI O( len / patlen ).

107.Pp
108See the specific manual pages for more information.
109For manipulating variable length generic objects as byte
110strings (without the null byte check), see
111.Xr bstring 3 .
112.Pp
113Except as noted in their specific manual pages,
114the string functions do not test the destination
115for size limitations.

31.Sh NAME
32.Nm strlcpy,
33.Nm strlcat
34.Nd size-bounded string copying and concatenation
35.Sh SYNOPSIS
36.Fd #include <string.h>
37.Ft size_t
38.Fn strlcpy "char *dst" "const char *src" "size_t size"
39.Ft size_t
40.Fn strlcat "char *dst" "const char *src" "size_t size"
41.Sh DESCRIPTION
42The
43.Fn strlcpy
44and
45.Fn strlcat
46functions copy and concatenate strings respectively. They are designed
47to be safer, more consistent, and less error prone replacements for
48.Xr strncpy 3
49and
50.Xr strncat 3 .
51Unlike those functions,
52.Fn strlcpy
53and
54.Fn strlcat
55take the full size of the buffer (not just the length) and guarantee to
56NUL-terminate the result (as long as
57.Fa size
58is larger than 0). Note that you should include a byte for the NUL in
59.Fa size .
60.Pp
61The
62.Fn strlcpy
63function copies up to
64.Fa size
65- 1 characters from the NUL-terminated string
66.Fa src
67to
68.Fa dst ,
69NUL-terminating the result.
70.Pp
71The
72.Fn strlcat
73function appends the NUL-terminated string
74.Fa src
75to the end of
76.Fa dst .
77It will append at most
78.Fa size
79- strlen(dst) - 1 bytes, NUL-terminating the result.
80.Sh RETURN VALUES
81The
82.Fn strlcpy
83and
84.Fn strlcat
85functions return the total length of the string they tried to
86create. For
87.Fn strlcpy
88that means the length of
89.Fa src .
90For
91.Fn strlcat
92that means the initial length of
93.Fa dst
94plus
95the length of
96.Fa src .
97While this may seem somewhat confusing it was done to make
98truncation detection simple.
99.Sh EXAMPLES
100The following code fragment illustrates the simple case:
101.Bd -literal -offset indent
102char *s, *p, buf[BUFSIZ];
103
104.Li ...
105
106(void)strlcpy(buf, s, sizeof(buf));
107(void)strlcat(buf, p, sizeof(buf));
108.Ed
109.Pp
110To detect truncation, perhaps while building a pathname, something
111like the following might be used:
112.Bd -literal -offset indent
113char *dir, *file, pname[MAXPATHNAMELEN];
114
115.Li ...
116
117if (strlcpy(pname, dir, sizeof(pname)) >= sizeof(pname))
118 goto toolong;
119if (strlcat(pname, file, sizeof(pname)) >= sizeof(pname))
120 goto toolong;
121.Ed
122.Pp
123Since we know how many characters we copied the first time, we can
124speed things up a bit by using a copy instead on an append:
125.Bd -literal -offset indent
126char *dir, *file, pname[MAXPATHNAMELEN];
127size_t n;
128
129.Li ...
130
131n = strlcpy(pname, dir, sizeof(pname));
132if (n >= sizeof(pname))
133 goto toolong;
134if (strlcpy(pname + n, file, sizeof(pname)) >= sizeof(pname) - n)
135 goto toolong;

37.Dt STRMODE 3
38.Os
39.Sh NAME
40.Nm strmode
41.Nd convert inode status information into a symbolic string
42.Sh SYNOPSIS
43.Fd #include <string.h>
44.Ft void
45.Fn strmode "mode_t mode" "char *bp"
46.Sh DESCRIPTION
47The
48.Fn strmode
49function
50converts a file
51.Fa mode
52(the type and permission information associated with an inode, see
53.Xr stat 2 )
54into a symbolic string which is stored in the location referenced by
55.Fa bp .
56This stored string is eleven characters in length plus a trailing
57.Dv NUL .
58.Pp
59The first character is the inode type, and will be one of the following:
60.Pp
61.Bl -tag -width flag -offset indent -compact
62.It \-
63regular file
64.It b
65block special
66.It c
67character special
68.It d
69directory
70.It l
71symbolic link
72.It p
73fifo
74.It s
75socket
76.It w
77whiteout
78.It ?
79unknown inode type
80.El
81.Pp
82The next nine characters encode three sets of permissions, in three
83characters each.
84The first three characters are the permissions for the owner of the
85file, the second three for the group the file belongs to, and the
86third for the ``other'', or default, set of users.
87.Pp
88Permission checking is done as specifically as possible.
89If read permission is denied to the owner of a file in the first set
90of permissions, the owner of the file will not be able to read the file.
91This is true even if the owner is in the file's group and the group
92permissions allow reading or the ``other'' permissions allow reading.
93.Pp
94If the first character of the three character set is an ``r'', the file is
95readable for that set of users; if a dash ``\-'', it is not readable.
96.Pp
97If the second character of the three character set is a ``w'', the file is
98writable for that set of users; if a dash ``\-'', it is not writable.
99.Pp
100The third character is the first of the following characters that apply:
101.Bl -tag -width xxxx
102.It S
103If the character is part of the owner permissions and the file is not
104executable or the directory is not searchable by the owner, and the
105set-user-id bit is set.
106.It S
107If the character is part of the group permissions and the file is not
108executable or the directory is not searchable by the group, and the
109set-group-id bit is set.
110.It T
111If the character is part of the other permissions and the file is not
112executable or the directory is not searchable by others, and the ``sticky''
113.Pq Dv S_ISVTX
114bit is set.
115.It s
116If the character is part of the owner permissions and the file is
117executable or the directory searchable by the owner, and the set-user-id
118bit is set.
119.It s
120If the character is part of the group permissions and the file is
121executable or the directory searchable by the group, and the set-group-id
122bit is set.
123.It t
124If the character is part of the other permissions and the file is
125executable or the directory searchable by others, and the ``sticky''
126.Pq Dv S_ISVTX
127bit is set.
128.It x
129The file is executable or the directory is searchable.
130.It \-
131None of the above apply.
132.El
133.Pp
134The last character is a plus sign ``+'' if there are any alternate
135or additional access control methods associated with the inode, otherwise
136it will be a space.
137.Sh RETURN VALUES
138The
139.Fn strmode
140function
141always returns 0.
142.Sh SEE ALSO
143.Xr chmod 1 ,
144.Xr find 1 ,
145.Xr stat 2 ,
146.Xr getmode 3 ,
147.Xr setmode 3
148.Sh HISTORY
149The
150.Fn strmode
151function first appeared in
152.Bx 4.4 .

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

42.Nm strtok ,
43.Nm strsep

45.Sh SYNOPSIS
46.Fd #include <string.h>
47.Ft char *
48.Fn strtok "char *str" "const char *sep"
49.Sh DESCRIPTION
50.Bf -symbolic
51This interface is obsoleted by
52.Xr strsep 3 .
53.Ef
54.Pp
55The
56.Fn strtok
57function
58is used to isolate sequential tokens in a null-terminated string,
59.Fa str .
60These tokens are separated in the string by at least one of the
61characters in
62.Fa sep .
63The first time that
64.Fn strtok
65is called,
66.Fa str
67should be specified; subsequent calls, wishing to obtain further tokens
68from the same string, should pass a null pointer instead.
69The separator string,
70.Fa sep ,
71must be supplied each time, and may change between calls.
72.Pp
73The
74.Fn strtok
75function
76returns a pointer to the beginning of each subsequent token in the string,
77after replacing the separator character itself with a
78.Dv NUL
79character.
80When no more tokens remain, a null pointer is returned.
81.Sh SEE ALSO
82.Xr index 3 ,
83.Xr memchr 3 ,
84.Xr rindex 3 ,
85.Xr strchr 3 ,

87.Xr strpbrk 3 ,
88.Xr strrchr 3 ,
89.Xr strsep 3 ,
90.Xr strspn 3 ,
91.Xr strstr 3
92.Sh STANDARDS
93The
94.Fn strtok
95function
96conforms to
97.St -ansiC .
98.Sh BUGS
99There is no way to get tokens from multiple strings simultaneously.
100.Pp
101The System V
102.Fn strtok ,
103if handed a string containing only delimiter characters,
104will not alter the next starting point, so that a call to
105.Fn strtok
106with a different (or empty) delimiter string
107may return a
108.Pf non- Dv NULL
109value.
110Since this implementation always alters the next starting point,
111such a sequence of calls would always return
112.Dv NULL .
