I seem to be having trouble getting information passed into
a signal interrupt handler.  I want more than just the
signal number.  According to the sigaction man page, I should be
able to do something like the following...

declare a signal handler function like so:

void sig_handler(int sig, siginfo_t *si, void *ctxt)
{
        blah blah blah

Quote:}

    struct sigaction act, oact;

    act.sa_sigaction = sig_handler;
    act.sa_flags = SA_SIGINFO;
    sigemptyset(&act.sa_mask);

    sigaction(SIGPIPE, &act, &oact);

So, when a SIGPIPE (Also tried SIGINT) is generated I want
the siginfo structure in the handler to be non-NULL.  However,
every time I generate the SIGPIPE or SIGINT (when installed)
the 2nd argument in the handler (struct siginfo *si) is always
NULL.

Any ideas what is happening, why can't I get this structure
to be non-NULL??
