There are 3 major differences between Mutex and Binary
semaphore.....

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.

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.
