Synchronization of three streams in a specific queue with Mutex

there is a slight problem with threads, please tell me how to solve it or at least in which direction to look for, looking for a long time, but so far without success ... Here's the problem: there are 3 threads, they can run in any order (321;213;123...). In whatever order flows we would not run, they need to work out in the order 1,2,3. For this purpose, use thread synchronization with ONE mutex. In advance thank you.

use mutex to protect a global integer, iThread. Init iThread to 1. create threads, pass in an id for each thread: 1,2,3.

In thread proc, lock mutex to check iThread. If iThread != thread id, then wait on condition.

if iThread = thread id: unlock mutex, execute work in threadproc; at end of thread proc: lock mutex, ++iThread, and signal condition, unlock mutex.

something like that. There are a million other ways.
