  This problem isn't particularly interesting in C. It only becomes interesting in the context of some operating system environment where threads or processes exist in the face of pre-emptive switching. I've no idea what calls you are permitted to make here. Are you implementing a "lock" using a binary semaphore? I don't know. Also, the design you provided doesn't seem workable. Suppose producer grabs 'mutex' and then sits waiting on 'parent' to be notified/signaled. The consumer can't get mutex, so it can't signal. What you have looks like half of a monitor-based system. But I don't see the monitor. See link below for a reasonable discussion here.
