    Can somebody provide me example of starting and stop an userdefined timer on PTHREAD concepts ?

    Basically, like this. one thread started TIMER1, now other thread on TIMER1 with value x need to stop the TIMER1 and start TIMER2.

    Please help me.

    for ex:

    In the following program, can somebody suggest me to start another THREAD and cancel the the timer which i started currently when it is delayed for 3secs.

    Code:
    struct timeval tv; 
    
    int set_timer(struct timeval &tv,time_t sec)
    {
     gettimeofdat(&tv,NULL);
     tv.tv_sec += sec;
     return 1;
    }
    
    void* timer(void* arg)
    {
       set_timer(tv,5);
    }
      
    int main(int argc, char* argv[])  
     {  
     
    pthread_create (&thread_id, NULL,&timer,NULL);
    pthread_join(&thread_id);
    
    }
