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


#include <wchar.h>

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


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

Return Value

The wcscasecmp() function shall return 0 if the wide-character strings s1 and s2 are equal except for case distinctions. It shall return a positive integer if s1 is greater than s2, ignoring case. It shall return a negative integer if s1 is less than s2, ignoring case.


The behavior of wcscasecmp() depends upon the LC_CTYPE category of the current locale.
