Question

I have an application which starts 5 threads.

After starting those threads nothing happens in main().

main(){
      `start thread 1..5
}

How do I loop infinitely in main() so my program will run continuously until it gets a signal.

I don’t want to use

while(true)

because it will eat CPU cycle. (As I think )

Edit:
I am using gcc 4
Thread Api :pthread
OS : Linux

Answer 1

the simplest would be:

while (true) sleep(1000);

and the best would be to join() all the five threads.
