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.
The wmemcpy() function shall return the value of ws1.
No errors are defined.
