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  character  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.
