DESCRIPTION

25       The wcpcpy() function is the wide-character equivalent of the stpcpy(3)
26       function.  It copies the wide-character string pointed to by  src,  in‐
27       cluding  the  terminating  null  wide  character  (L'\0'), to the array
28       pointed to by dest.
29
30       The strings may not overlap.
31
32       The programmer must  ensure  that  there  is  room  for  at  least  wc‐
33       slen(src)+1 wide characters at dest.
34

RETURN VALUE

36       wcpcpy()  returns  a  pointer  to  the end of the wide-character string
37       dest, that is, a pointer to the terminating null wide character.
