Question

I am using a timer in my C++ code through setitimer function from sys/time.h. This maps the SIGALRM signal to my timer handler method. After this I am not able to use sleep function. I am assuming it is because sleep uses SIGALRM signal as well. Can you suggest any workaround for this problem?

Thanks for replying.

You can try using select() just as a timer. I don’t know if it uses SIGALRM or not but it should be simple to test. Something like:

   timeval t = {1, 0};

   select(0, NULL, NULL, NULL, &t);
