The wmemcpy function is the wide-character equivalent of the memcpy function. It copies n wide characters from the array starting at src to the array starting at dest.
The arrays may not overlap; use wmemmove(3) to copy between overlapping arrays.
The programmer must ensure that there is room for at least n wide characters at dest.
wmemcpy returns dest.
