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
You can’t perform that action at this time.
