Providing/passing argument to signal handler

Question

Can I provide/pass any arguments to signal handler?

/* Signal handling */
struct sigaction act;
act.sa_handler = signal_handler;
/* some more settings */

I think you it's better to use SA_SIGINFO in sa_flags so the handler will get void signal_handler(int sig, siginfo_t *info, void *secret) in siginfo_t you can provide your params. Ty:HAPPY code
