FUNCTION
	<<wmemmove>>---copy wide characters in memory with overlapping areas 
 
ANSI_SYNOPSIS
	#include <wchar.h>
	wchar_t *wmemmove(wchar_t *<[d]>, const wchar_t *<[s]>, size_t <[n]>);
 
TRAD_SYNOPSIS
	wchar_t *wmemmove(<[d]>, <[s]>, <[n]>
	wchar_t *<[d]>;
	const wchar_t *<[s]>;
	size_t <[n]>;
 
DESCRIPTION
	The <<wmemmove>> function copies <[n]> wide characters from the object
	pointed to by <[s]> to the object pointed to by <[d]>. Copying takes
	place as if the <[n]> wide characters from the object pointed to by
	<[s]> are first copied into a temporary array of <[n]> wide characters
	that does not overlap the objects pointed to by <[d]> or <[s]>, and then
	the <[n]> wide characters from the temporary array are copied into the
	object pointed to by <[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
	The <<wmemmove>> function returns the value of <[d]>.
 
PORTABILITY
<<wmemmove>> is ISO/IEC 9899/AMD1:1995 (ISO C).
 
No supporting OS subroutines are required.
