       For  wcscpy(): 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 wcpcpy() and wcscpy() functions shall copy the wide-character string pointed to by ws2 (including the
       terminating null wide-character code) into the array pointed to by ws1.

       The  application  shall  ensure  that there is room for at least wcslen(ws2)+1 wide characters in the ws1
       array, and that the ws2 and ws1 arrays do not overlap.

       If copying takes place between objects that overlap, the behavior is undefined.

       No errors are defined.

       wcpcpy, wcscpy — copy a wide-character string, returning a pointer to its end

       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.

       None.

       The wcpcpy() function shall return a pointer to the terminating null wide-character code copied into  the
       ws1 buffer.

       The wcscpy() function shall return ws1.

       No return values are reserved to indicate an error.
