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.1‐2017 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
       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 wmemcpy() function shall return the value of ws1.
