| 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.
