       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.

       No errors are defined.

       may differ (consult the corresponding Linux manual page for details of Linux behavior), or the  interface
