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.
