Atomically unlock the specified `mutex` and suspend execution of the current thread until this condition object is "signaled" (i.e., either `signal` or `broadcast` is invoked on this object in another thread), then re‐acquire a lock on the `mutex`. Return 0 on success, and a non‐zero value otherwise. Spurious wakeups are rare but possible; i.e., this method may succeed (return 0), and return control to the thread without the condition object being signaled. The behavior is undefined unless `mutex` is locked by the calling thread prior to calling this method. Note that `mutex` remains locked by the calling thread upon return from this function.
