Linux Threads suspend/resume

Question

I\'m writing a code in which I have two threads running in parallel.

1st is the main thread which started the 2nd thread. 2nd thread is just a simple thread executin

Answer 1

You can use mutex to do that, pseudo code would be:

While (true) {
    /* pause resume */
    lock(my_lock); /* if this is locked by thread1, thread2 will wait until thread1 */
                   /* unlocks it */
    unlock(my_lock); /* unlock so that next iteration thread2 could lock */

    /* do actual work here */
}
