It compares the wide-character string pointed to by \fIs1\fP and the +wide-character string pointed to by \fIs2\fP, but at most \fIn\fP wide +characters from each string. In each string, the comparison extends only up +to the first occurrence of a L'\\0' character, if any. +.SH "RETURN VALUE" +The \fBwcsncmp\fP function returns zero if the wide-character strings at +\fIs1\fP and \fIs2\fP, truncated to at most length \fIn\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" +ISO/ANSI C, UNIX98 +.SH "SEE ALSO" +.BR strncmp (3), +.BR wcsncasecmp (3) |
