Answer Posted / prasenjit roy
Mutex is a locking object ( like a flag ) for avoiding the
simultaneous use of a common resource. It is also used to
lock the critical section.
Ctitical Section :: is a block of code which should run
atomically ie. there should be no contact switching while
this block executes and once the block starts it should
finish without any interruption.

I was a c++ code and was asked to find out the bug in that. The bug was that he declared an object locally in a function and tried to return the pointer to that object. Since the object is local to the function, it no more exists after returning from the function. The pointer, therefore, is invalid outside.
