It compares the \fIn\fP wide-characters starting at \fIs1\fP and the \fIn\fP wide-characters starting at \fIs2\fP. .SH "RETURN VALUE" The .BR wmemcmp () function returns zero if the wide-character arrays of size \fIn\fP at \fIs1\fP and \fIs2\fP are equal. It returns an integer greater than zero if at the first differing position \fIi\fP (\fIi\fP < \fIn\fP), the corresponding wide-character \fIs1[i]\fP is greater than \fIs2[i]\fP. It returns an integer less than zero if at the first differing position \fIi\fP (\fIi\fP < \fIn\fP), the corresponding wide-character \fIs1[i]\fP is less than \fIs2[i]\fP. .SH "CONFORMING TO" C99. .SH "SEE ALSO" .BR memcmp (3), .BR wcscmp (3)
