       This manual page is part of the POSIX Programmer's Manual.  The OS
       implementation of this interface may differ (consult the corresponding
       OS manual page for details of OS behavior), or the interface may not be
       implemented on OS.

       For _w_c_s_c_p_y(): 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 _w_c_p_c_p_y() and _w_c_s_c_p_y() functions shall copy the wide-character
       string pointed to by _w_s_2 (including the terminating null wide-character
       code) into the array pointed to by _w_s_1.

       The application shall ensure that there is room for at least
       _w_c_s_l_e_n(_w_s_2)+1 wide characters in the _w_s_1 array, and that the _w_s_2 and
       _w_s_1 arrays do not overlap.

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

RREETTUURRNN VVAALLUUEE
       The _w_c_p_c_p_y() function shall return a pointer to the terminating null
       wide-character code copied into the _w_s_1 buffer.

       The _w_c_s_c_p_y() function shall return _w_s_1.

       No return values are reserved to indicate an error.
