PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the  corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.
NAME
       wmemcpy -- copy wide characters in memory
SYNOPSIS
       #include <wchar.h>
       wchar_t *wmemcpy(wchar_t *restrict ws1, const wchar_t *restrict ws2,
           size_t n);
DESCRIPTION
       The functionality described on this reference page is aligned with  the
       ISO C  standard.  Any  conflict between the requirements described here
       and the ISO C standard is unintentional. This  volume  of  POSIX.1-2008
       defers to the ISO C standard.
       The  wmemcpy()  function  shall  copy n wide characters from the object
       pointed to by ws2 to the object pointed to by ws1.  This function shall
       not be affected by locale and all wchar_t values shall be treated iden-
       tically. 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 wmemcpy() function shall return the value of ws1.
