Hi ghc users, I have a program, written in a mixture of Haskell and C, in which the C part is supposed to handle a ^C interrupt, accomplished through the usual signal() call. It works as expected when the Haskell part is compiled by nhc98. But when it is compiled by ghc, for some reason the ghc RTS appears to trap the interrupt itself, and halts the program with the message prog: interrupted instead of allowing the newly installed C signal handler to run. I have looked through the ghc user manual for some means to turn off or divert the RTS signal-handling, but I couldn't find anything relevant. The nearest thing is Exception.block, which excludes an asynchronous exception from happening whilst the `block' is in operation, but that doesn't seem to stop a ^C from interrupting the program, so I guess that isn't its real purpose. So, what should I use instead? Regards, Malcolm
