I have a question regarding signals. Is there a way you can pass some custom defined parameter (say, a struct foo * ) to a signal handler?? To be more specific, struct sigaction defines 2 types of handlers - namely sa_handler and sa_sigaction both of which have predefined set of arguments to them. sa_handler has (int) as the argument and sa_sigaction has (int, siginfo_t *, void *) as its arguments. The third argument void * to sa_sigaction is for a ucontext_t struct that contains the process's context at the time of signal delivery. My requirement is: I need to pass a struct foo * pointer to the signal handler when I set it up and later when the signal is delivered I must be able to see the foo * that I had passed at the time of setting up the handler. Does anyone know how we can do this?
