in the following program I have observed that the program is not jumped on the handler but if i remove the statement sleep(1); it work fine.

the piece of the code is

…

while(1)

{

if (flag)

printf(“waiting for signal”);

else

printf(“signal invoked”);

sleep(1);

}

my question is when we press Ctrl+C (generating a signal) in such case the program should moved to signal handler function but in this case why it is not working correctly while having sleep(1); statement there why it is so?
