Cooperating Processes Mechanisms for inter-process communication enable different processes to exchange information and synchronize their actions. Semaphores enable concurrent accesses to shared resources such as files and I/O devices by multiple processes. A single ordinary (unnamed) pipe provides a solution for bidirectional communication between related processes.
