Use a condition variable to tell your thread from your "main" function,
that it should now run. Just before returning from the function, signal
the thread using pthread_cond_signal() or pthread_cond_broadcast().

The first thing that your thread should do is to wait on the condition
variable using pthread_cond_wait().

The predicate associated to the condition variable could be something
like thread_runable, which becomes true when the "main" function is
about to return.

HTH,
