In local.libraries, you wrote:
solution: add another argument to Posix.installHandler which takes a list of flags as described in sigaction(3) (including SA_ONESHOT). I apologize if i am misinterpreting the behavior of my program.
I'm not sure that the other flags are (generally) useful or apply at all to Haskell (e.g. SA_NODEFER: is a Haskell-handler equivalent to a C signal handler?). Furthermore, it's probably not necessary to break the API. How about a new function with the parameter indicating ONESHOT or not and then expressing installHandler through this? I don't like primInstallHandler or installHandler', so if somebody has a suggestion... BTW: One might argue that you could simply write your own in-Haskell signalstack by simply setting MVars/Semaphores in the signal handler and then have one Concurrent Haskell thread which decides what to do with those 'signals'. -- http://www-i2.informatik.rwth-aachen.de/stolz/ *** PGP *** S/MIME
