It compares the wide-character string pointed to by \fIs1\fP and the wide-character string pointed to by \fIs2\fP, ignoring case differences (\fBtowupper\fP(), \fBtowlower\fP()). .SH "RETURN VALUE" The \fBwcscasecmp\fP() function returns zero if the wide-character strings at \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. .SH "CONFORMING TO" This function is a GNU extension. .SH "SEE ALSO" .BR strcasecmp (3), .BR wcscmp (3) .SH NOTES The behaviour of \fBwcscasecmp\fP() depends on the LC_CTYPE category of the current locale.
