Condition Variables

Code examples from condition variables chapter. Build by typing make;
run the resulting executable to see how it works. Insert sleep() calls
of various lengths to control timing and force bad things to happen.

Fork/Join Problem

• join_spin.c: Working solution but wastes CPU.
• join_no_lock.c: What happens when you don't put a lock around the state change and signal
• join_no_state_var.c: What happens if you don't have a state variable
• join.c: A working solution
• join_modular.c: A modularized version

Producer/Consumer Problem

• pc_single_cv.c: What happens if you only use one condition variable
• pc.c: A working solution
