The man pages were rather inconsistent in the use of "Unix"
versus "UNIX". Let's go with the trademark usage.

.SH DESCRIPTION
|
2007-05-12 09:06:04 +00:00
|
|
|
The
|
|
|
|
.BR wcscasecmp ()
|
|
|
|
function is the wide-character equivalent of the
|
|
|
|
.BR strcasecmp (3)
|
|
|
|
function.
|
2007-04-12 22:42:49 +00:00
|
|
|
It compares the wide-character string pointed to
|
2004-11-03 13:51:07 +00:00
|
|
|
by \fIs1\fP and the wide-character string pointed to by \fIs2\fP, ignoring
|
2007-05-12 09:06:04 +00:00
|
|
|
case differences
|
|
|
|
.RB ( towupper (3),
|
|
|
|
.BR towlower (3)).

.SH "RETURN VALUE"
|
2007-05-12 09:06:04 +00:00
|
|
|
The
|
|
|
|
.BR wcscasecmp ()
|
|
|
|
function returns zero if the wide-character strings at
|
2007-04-12 22:42:49 +00:00
|
|
|
\fIs1\fP and \fIs2\fP are equal except for case distinctions.
|
|
|
|
It returns a
|
|
|
|
positive integer if \fIs1\fP is greater than \fIs2\fP, ignoring case.
|
|
|
|
It
|
|
|
|
returns a negative integer if \fIs1\fP is smaller
|
|
|
|
than \fIs2\fP, ignoring case.
