wmemcmp

int wmemcmp(const wchar_t *s1, const wchar_t *s2, size_t n);

The function compares successive elements from two arrays beginning at the addresses s1 and s2 (both of size n), until it finds elements that are not equal.

• If all elements are equal, the function returns zero.
• If the differing element from s1 is greater than the element from s2, the function returns a positive number.
• Otherwise, the function returns a negative number.
