A counting semaphore handles multiple identical resources, allowing a specified number of threads to access the pool concurrently. Its primary rule is that only one thread can hold the mutex at any given time.
Semaphore Versus Mutex: Thread Safety Explained
Variants and Use Cases Semaphores are generally categorized into two types: binary and counting. This characteristic makes a mutex ideal for protecting critical sections where a clear owner is required.
Defining the Semaphore: Managing Access Count Unlike a mutex, a semaphore is a signaling mechanism that manages access based on a counter. If another thread attempts to lock an already locked mutex, it will block until the owning thread releases it by "unlocking" it.

It answers the question of "how many" rather than "who. Deadlocks also remain a risk with both if the acquisition order is not managed properly.
