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.
