WMEMMOVE(3P)                                        POSIX Programmer's Manual                                       WMEMMOVE(3P)



PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (con-
       sult the corresponding Linux manual page for details of Linux behavior), or the  interface  may  not  be  implemented  on
       Linux.

NAME
       wmemmove - copy wide characters in memory with overlapping areas

SYNOPSIS
       #include <wchar.h>

       wchar_t *wmemmove(wchar_t *ws1, const wchar_t *ws2, size_t n);


DESCRIPTION
       The  wmemmove()  function shall copy n wide characters from the object pointed to by ws2 to the object pointed to by ws1.
       Copying shall take place as if the n wide characters from the object pointed to by ws2 are first copied into a  temporary
       array  of  n  wide  characters that does not overlap the objects pointed to by ws1 or ws2, and then the n wide characters
       from the temporary array are copied into the object pointed to by ws1.

       This function shall not be affected by locale and all wchar_t values shall be treated identically. The null wide  charac-
       ter and wchar_t values not corresponding to valid characters shall not be treated specially.

       If  n  is  zero,  the application shall ensure that ws1 and ws2 are valid pointers, and the function shall copy zero wide
       characters.

RETURN VALUE
       The wmemmove() function shall return the value of ws1.
