Whats is the difference between AutoResetEvent and Mutex

I am new to these concepts. But as i am going deeper in threading i am getting confused.

What is the significance of mutex, semaphore over autoresetevent.

Only difference i came to know with studies is that a mutex can perform across process operations. If this is the case why it does not have same method as Set, Reset, WaitOne.

Can we replace the AutoResetEvent with mutex and vice versa?

Please solve this puzzle.

Solution

  • Different concept - a Mutex is an exclusive token; only one person can have it; when they release it, somebody else can fight over it. An AutoResetEvent is a gate that allows exactly one person through before closing, and which is operated by a button that is separate to the queue of people wanting to go through. When they pass through the gate immediately closes.
