The wmemset() function shall copy the value of wc into
each of the first n wide characters of the object
pointed to by ws. 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 ws is
a valid pointer, and the function shall copy zero wide
The wmemset() functions shall return the value of ws.
No errors are defined.
