+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.
