12 .TH STRCOLL 3C "Nov 1, 2003"
13 .SH NAME
14 strcoll \- string collation
15 .SH SYNOPSIS
16 .LP
17 .nf
18 #include <string.h>
19
20 \fBint\fR \fBstrcoll\fR(\fBconst char *\fR\fIs1\fR, \fBconst char *\fR\fIs2\fR);
21 .fi
22
23 .SH DESCRIPTION
24 .sp
25 .LP
26 Both \fBstrcoll()\fR and \fBstrxfrm\fR(3C) provide for locale-specific string
27 sorting. \fBstrcoll()\fR is intended for applications in which the number of
28 comparisons per string is small. When strings are to be compared a number of
29 times, \fBstrxfrm\fR(3C) is a more appropriate function because the
30 transformation process occurs only once.
31 .sp
32 .LP
33 The \fBstrcoll()\fR function does not change the setting of \fBerrno\fR if
34 successful.
35 .sp
36 .LP
37 Since no return value is reserved to indicate an error, an application wishing
38 to check for error situations should set \fBerrno\fR to 0, then call
39 \fBstrcoll()\fR, then check \fBerrno\fR.
40 .SH RETURN VALUES
41 .sp
42 .LP
43 Upon successful completion, \fBstrcoll()\fR returns an integer greater than,
44 equal to, or less than zero in direct correlation to whether string \fIs1\fR is
45 greater than, equal to, or less than the string \fIs2\fR. The comparison is
46 based on strings interpreted as appropriate to the program's locale for
47 category \fBLC_COLLATE\fR (see \fBsetlocale\fR(3C)).
48 .sp
49 .LP
50 On error, \fBstrcoll()\fR may set \fBerrno\fR, but no return value is reserved
51 to indicate an error.
52 .SH ERRORS
53 .sp
54 .LP
55 The \fBstrcoll()\fR function may fail if:
56 .sp
57 .ne 2
58 .na
59 \fB\fBEINVAL\fR\fR
60 .ad
61 .RS 10n
62 The \fIs1\fR or \fIs2\fR arguments contain characters outside the domain of the
63 collating sequence.

28 .SH DESCRIPTION
29 .LP
30 Both \fBstrcoll()\fR and \fBstrxfrm\fR(3C) provide for locale-specific string
31 sorting. \fBstrcoll()\fR is intended for applications in which the number of
32 comparisons per string is small. When strings are to be compared a number of
33 times, \fBstrxfrm\fR(3C) is a more appropriate function because the
34 transformation process occurs only once.
35 .LP
36 The \fBstrcoll_l()\fR function behaves
37 identically to \fBstrcoll()\fR, except instead of operating in the current
38 locale, it operates in the locale specified by \fIloc\fR.
39 .LP
40 The \fBstrcoll()\fR function does not change the setting of \fBerrno\fR if
41 successful.
42 .LP
43 Since no return value is reserved to indicate an error, an application wishing
44 to check for error situations should set \fBerrno\fR to 0, then call
45 \fBstrcoll()\fR, then check \fBerrno\fR.
