FUNCTION
|
|
<<wmemmove>>---copy wide characters in memory with overlapping areas
|
|
|
|
SYNOPSIS
|
|
#include <wchar.h>
|
|
wchar_t *wmemmove(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.
