wcscasecmp -- compare two wide-character strings, ignoring case


#include <wchar.h>

int wcscasecmp(const wchar_t *s1, const wchar_t *s2);


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.


The behavior of wcscasecmp depends on the LC_CTYPE category of the current locale.
