PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the  corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.
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 charac-
       ter 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.
