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 shall compare 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 shall not be affected  by  locale
       and  all  wchar_t  values  shall  be  treated identically. The null wide character and wchar_t values not
       corresponding to valid characters shall not be treated specially.

       If n is zero, the application shall ensure that ws1 and ws2 are valid pointers, and  the  function  shall
       behave as if the two objects compare equal.


RETURN VALUE
       The  wmemcmp()  function shall return an integer greater than, equal to, or less than zero, respectively,
       as the object pointed to by ws1 is greater than, equal to, or less than the object pointed to by ws2.
