FUNCTION
        <<wmempcpy>>---copy wide characters in memory and return end pointer

SYNOPSIS
        #define _GNU_SOURCE
        #include <wchar.h>
        wchar_t *wmempcpy(wchar_t *<[d]>,
                         const wchar_t *<[s]>, size_t <[n]>);

DESCRIPTION
        The <<wmemcpy>> function copies <[n]> wide characters from the object
        pointed to by <[s]> to the object pointed to be <[d]>. 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, <[d]> and <[s]> must be a valid pointers, and the
        function copies zero wide characters.

RETURNS
        <<wmempcpy>> returns a pointer to the wide character following the
        last wide character copied to the <[out]> region.

PORTABILITY
<<wmempcpy>> is a GNU extension.

No supporting OS subroutines are required.
