a valid file descriptor, use file descriptor operations, else use
filename based operations on SRC_NAME. Likewise for DEST_DESC and

If access control lists are not available, fchmod the target file to
MODE. Also sets the non-permission bits of the destination file
(S_ISUID, S_ISGID, S_ISVTX) to those from MODE if any are set.
