FUNCTION
<<wmemmove>>---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.
