A condition variable is a synchronization primitive that allows threads to wait until a particular condition is fulfilled. The wait operation blocks the thread until another thread signals or broadcasts about the occurrence of an event or condition. A mutex is a locking mechanism that prevents multiple threads from accessing shared resources simultaneously. A general semaphore is a synchronization mechanism that controls access to a finite number of resources. Deadlock occurs when two or more competing threads are blocked, each waiting for a resource held by the other, causing all threads to freeze. Therefore, the best choice for a data type that necessarily blocks a process or thread until a particular condition is true is a condition variable.
