How do I set-up non-blocking I/O with SIGIO or
SIGURG notifications under Cygwin?

The various Unices I know of use either F_SETFL+F_SETOWN
(BSD-ish), I_SETSIG (STREAMS-ish), FIOASYNC+SIOCSPGRP, or
FIOASYNC (but does this send signals?).  Does any
of these work with Cygwin or do I need another one?

Also, what kinds of file handlers will it work on?  Does it
work on sockets and tty's at least?

Thanks in advance,

Paolo Bonzini
