.SH DESCRIPTION
|
|
The
|
|
.BR strcoll ()
|
|
function compares the two strings \fIs1\fP and
|
|
\fIs2\fP.
|
|
It returns an integer less than, equal to, or greater
|
|
than zero if \fIs1\fP is found, respectively, to be less than,
|
|
to match, or be greater than \fIs2\fP.
|
|
The comparison is based on
|
|
strings interpreted as appropriate for the program's current locale
|
|
for category \fBLC_COLLATE\fP. (See
|
|
.BR setlocale (3).)
|
|

|
|
than, to match, or be greater than \fIs2\fP, when both are interpreted
|
