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

77In this implementation
78.Fn memcpy
79is implemented using

81and therefore the strings may overlap.
82On other systems, copying overlapping strings may produce surprises.
83A simpler solution is to not use

42.Sh NAME
43.Nm strftime
44.Nd format date and time
45.Sh SYNOPSIS
46.Fd #include <time.h>
47.Ft size_t
48.Fn strftime "char *buf" "size_t maxsize" "const char *format" "const struct tm *timeptr"
49.Sh DESCRIPTION
50The
51.Fn strftime
52function formats the information from
53.Fa timeptr
54into the buffer
55.Fa buf
56according to the string pointed to by
57.Fa format .
58.Pp
59The
60.Fa format
61string consists of zero or more conversion specifications and
62ordinary characters.
63All ordinary characters are copied directly into the buffer.
64A conversion specification consists of a percent sign
65.Ql %
66and one other character.
67.Pp
68No more than
69.Fa maxsize
70characters will be placed into the array.
71If the total number of resulting characters, including the terminating
72null character, is not more than
73.Fa maxsize ,
74.Fn strftime
75returns the number of characters in the array, not counting the
76terminating null.
77Otherwise, zero is returned.
78.Pp
79Each conversion specification is replaced by the characters as
80follows which are then copied into the buffer.
81.Bl -tag -width "xxxx"

105The string functions
106functions manipulate strings terminated by a
107null byte.
108.Pp
109See the specific manual pages for more information.
110For manipulating variable length generic objects as byte
111strings (without the null byte check), see
112.Xr bstring 3 .
113.Pp
114Except as noted in their specific manual pages,
115the string functions do not test the destination
116for size limitations.

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

51.Bf -symbolic
52This interface is obsoleted by 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.

93The

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 .
