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 __________________________________________________ Do You Yahoo!?
