wcscasecmp - compare two wide-character strings, ignoring case

Synopsis

#include <wchar.h>
int wcscasecmp(const wchar_t *s1, const wchar_t *s2);

Description

The wcscasecmp() function is the wide-character equivalent of the strcasecmp() function. It compares the wide-character string pointed to by s1 and the wide-character string pointed to by s2, ignoring case differences (towupper(), towlower()).

Return Value

The wcscasecmp() function returns zero if the wide-character strings at s1 and s2 are equal except for case distinctions. It returns a positive integer if s1 is greater than s2, ignoring case. It returns a negative integer if s1 is smaller than s2, ignoring case.

Conforming to

This function is a GNU extension.

Notes

The behaviour of wcscasecmp() depends on the LC_CTYPE category of the current locale.
