```wmemcmp(3C)						   Standard C Library Functions 					       wmemcmp(3C)

NAME
wmemcmp - compare wide-characters in memory

SYNOPSIS
#include <wchar.h>

int wmemcmp(const wchar_t *ws1, const wchar_t *ws2, size_t n);

DESCRIPTION
The  wmemcmp()  function  compares the first n wide-characters of the object pointed to by ws1 to the first n wide-characters of the object
pointed to by ws2. 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,  ws1 and ws2 must be a valid pointers and the function behaves as if the two objects compare equal.

RETURN VALUES
The  wmemcmp()  function  returns an integer greater than, equal to, or less than 0, accordingly as the object pointed to by ws1 is greater
than, equal to, or less than the object pointed to by ws2.

ERRORS
No errors are defined.
