No, because you can have polled gii devices. These need not correspond to a
fildescriptor or similar entity at all. You would have to spawn off a thread
or process to do that polling.
Actually it is what the one who answered previously is suggesting.
If you want a SIGIO when something comes up, the spawned-off thread that
keeps selecting for new input can send you one. Should be relatively simple.
