Hi there. Peering at the Posix stuff on process handling, I wrote the
following program:
import Posix
main
= do installHandler sigINT Ignore Nothing
loop
loop = do putStr ""
loop
This ought to loop forever (yup), ignoring any SIG_INT's (nup). Is the
above fundamentally misconceived in some hideous way that I have failed
to spot?
Blocking and catching seem to work fine and as I'd expect, but I don't
see how to get much useful functionality from just those two, if Ignore
can't be persuaded to work.
Is this a bug in the posix lib, or is my admittedly sketchy notion of
handling Unix interrupts letting me down?
Slainte,
Alex.
