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

The wcscmp() function is the wide-character equivalent of the strcmp(3)
function. It compares the wide-character string pointed to by s1 and
the wide-character string pointed to by s2.
RETURN VALUE
The wcscmp() function returns zero if the wide-character strings at s1
and s2 are equal. It returns an integer greater than zero if at the
first differing position i, the corresponding wide-character s1[i] is
greater than s2[i]. It returns an integer less than zero if at the
first differing position i, the corresponding wide-character s1[i] is
less than s2[i].
