| .SH NAME |
| wcscasecmp \- compare two wide-character strings, ignoring case |
| .SH SYNOPSIS |
| .nf |
| .B #include <wchar.h> |
| .sp |
| .BI "int wcscasecmp(const wchar_t *" s1 ", const wchar_t *" s2 ); |
| .fi |
| .SH DESCRIPTION |
| The \fBwcscasecmp\fP() function is the wide-character equivalent of the |
| \fBstrcasecmp\fP() function. 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 NOTES |
| The behaviour of \fBwcscasecmp\fP() depends on the LC_CTYPE category of the |
| current locale. |
