SYNOPSIS
#include <wchar.h>
int wmemcmp(const wchar_t *S1, const wchar_t *S2, size_t N);
DESCRIPTION
The `wmemcmp' function compares the first N wide characters of the
object pointed to by S1 to the first N wide characters of the object
pointed to by S2. This function is not affected by locale and all
wchar_t values are treated identically. The null wide character and
wchar_t values not corresponding to valid characters are not treated
specially.
If N is zero, S1 and S2 must be a valid pointers and the function
behaves as if the two objects compare equal.
RETURNS
The `wmemcmp' function returns an integer greater than, equal to, or
less than zero, accordingly as the object pointed to by S1 is greater
than, equal to, or less than the object pointed to by S2.
