Confusing the two can lead to subtle bugs, such as priority inversion or deadlock, making it essential to clarify their specific roles. Variants and Use Cases Semaphores are generally categorized into two types: binary and counting.
Semaphore Versus Mutex Deadlock Risk: Understanding the Hidden Dangers
Conversely, using a semaphore where a mutex is required can break data integrity, as multiple threads could enter a critical section believing they own the resource. Using a mutex where a semaphore is needed might unnecessarily restrict access to a resource that could handle multiple concurrent users.
Its primary rule is that only one thread can hold the mutex at any given time. This counter represents the number of permits available for a particular resource.

It answers the question of "how many" rather than "who. The two primary operations are "wait" (or "acquire") and "post" (or "release").
