Regrading signal/sigaction.

[siva kumar]

Hi,

Is it possible to pass any local variable as an
argument in the signal handler function.Basically I
want to print the value of the local variable in the
signal handler function.

In the below program I want to print the value of a in
the timeout function(siganl handler), whenever the
Alaram signal send.

Your comment are welcomed.

My prototype code is:

#include<stdio.h>
#include<signal.h>
void timeout(int signo,int a)
{
        printf ("timeout");
        printf("the value is %d and %d",signo,a);
}
 
main()
{
        int a =5;
        struct sigaction act,oact;
        act.sa_handler = timeout;
        sigemptyset(&act.sa_mask);
        act.sa_flags = 0;
        sigaction(SIGALRM, &act, &oact);
 
        alarm(10);
        sleep(10);
 
}

Thanks,
siva.s
