What is the difference between semaphores and mutex provided by pthread library ?
semaphores have a synchronized counter and mutex’s are just binary (true / false).
A semaphore is often used as a definitive mechanism for answering how many elements of a resource are in use — e.g., an object that represents n worker threads might use a semaphore to count how many worker threads are available.
Truth is you can represent a semaphore by an INT that is synchronized by a mutex.
