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.
