DESCRIPTION
The wcpcpy() function is the wide-character equivalent of the stpcpy(3)
function. It copies the wide-character string pointed to by src, in-
cluding the terminating null wide character (L'\0'), to the array
pointed to by dest.
The strings may not overlap.
The programmer must ensure that there is room for at least wc-
slen(src)+1 wide characters at dest.
RETURN VALUE
wcpcpy() returns a pointer to the end of the wide-character string
dest, that is, a pointer to the terminating null wide character.
