WebMar 1, 2024 · The mutex class is a synchronization primitive that can be used to protect shared data from being simultaneously accessed by multiple threads. mutex offers exclusive, non-recursive ownership semantics: A calling thread owns a mutex from the time that it successfully calls either lock or try_lock until it calls unlock . WebP1 waits on A. P2 fills buffer. P2 signals A and waits on B. P1 handles buffer data then signals B and loops back to wait on A again. – Martin James.
