wmemcmp - compare two arrays of wide-characters
int wmemcmp(const wchar_t *s1, const wchar_t *s2, size_t n);
The wmemcmp() function is the wide-character equivalent of the memcmp(3) function. It
compares the n wide-characters starting at s1 and the n wide-characters starting at s2.
The wmemcmp() function returns zero if the wide-character arrays of size n at s1 and s2
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].
Multithreading (see pthreads(7))
The wmemcmp() function is thread-safe.
