Question

I have a C program in which I use pthread.

I would like newly created threads to run as soon as they are created.

The reason behind this is that my threads have initialisation code to set up signal handlers, and I must be sure the handlers are ready, before my main thread sends some signals.

I’ve tried doing pthread_yield just after my pthread_create, but without success.

I doubt it makes a difference, but I am running Linux 3.6 on x86_64.

Thanks

Or you might use a barrier, i.e. call pthread_barrier_wait (early in the routine of each thread, or at initialization in the main thread), to ensure that every relevant thread has reached the barrier (after which some of your threads could do your naughty signal tricks). See this question.
