wcsncmp - compare two fixed-size wide-character strings
int wcsncmp(const wchar_t *s1, const wchar_t *s2, size_t n);
The wcsncmp function is the wide-character equivalent of the strncmp
function. It compares the wide-character string pointed to by s1 and
the wide-character string pointed to by s2, but at most n wide charac-
ters from each string. In each string, the comparison extends only up
to the first occurrence of a L'\0' character, if any.
The wcsncmp function returns zero if the wide-character strings at s1
and s2, truncated to at most length n, are equal. It returns an inte-
ger greater than zero if at the first differing position i (i < n), 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 (i < n),
the corresponding wide-character s1[i] is less than s2[i].
