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
characters 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 integer 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].
