    Unhappy Question about signal handler.

    Excuse me!
    I have a question about signal handler. There is a signal handler in sigaction structure such as:

    struct sigaction {
    unsigned int sa_flags;
    __sighandler_t sa_handler;
    sigset_t sa_mask;

    and I check the prototype of __sighandler_t is:

    typedef void __signalfn_t(int);
    typedef __signalfn_t __user *__sighandler_t;

    I cannot find any signal mechanism that pass argument to the int parameter in signal handler. How could I utilize this int parameter?

    Thanks for your favor.

    Ok, I have figured out that signal identify number would be passed to the int patameter in signal handler.
