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).
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.
This function is a
GNU extension.
