What is the difference between mutex and semaphore?..

Answer / ravichand

There are 3 major differences between Mutex and Binary
semaphore.....
1. In case of Mutex semaphore the task that had taken the
semaphore can only give it, however in the case of binary
semaphore any task can give the semaphore.

2. Calling SemFlush() function in Mutex is illegal.

3. Mutex Semaphore can not be given from an ISR.

What is the difference between mutex and semaphore?..

Answer / answers

Mutex: Nothing but a binary semaphore.
Mutex definition says "Mutex can lock any number of times,
and also it should unlock any number of times"---meaning,
in re-entrant codes if recursive is used.

In this case it will lock number of times and also should
unlock same number of times.

Semaphore: i think its default-----reeated answers.
