I need to add more information:
 Each of the two pthreads are launched from main. Each pthread stays
in a infinite loop. One of the pthreads listens on a socket for
incoming information from other servers (this could be many) and
populates several structures with the information. The second pthread
analyzes the information in the structures and if needed updates the
other servers. Since both pthread launch at the same time the thread
that is analyzing the data could attempt to grab data that is not
fully obtained yet which reeks havoc on the computations. I would be
able to re-write the routines and call one thread from inside the
other but that would eat more processing power in thread creation and
destruction. Besides you never know what the future will hold so  need
to grasp a better understanding of how to control this beast "pthreads". 

Thanks
