+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.
