Answer Posted / jitendra
An object of class CMutex represents a "mutex" ? a
synchronization object that allows one thread mutually
exclusive access to a resource. Mutexes are useful when
only one thread at a time can be allowed to modify data or
some other controlled resource. For example, adding nodes
to a linked list is a process that should only be allowed
by one thread at a time. By using a CMutex object to
control the linked list, only one thread at a time can gain
access to the list.
An object of class CSemaphore represents a "semaphore" ? a
synchronization object that allows a limited number of
threads in one or more processes to access a resource. A
CSemaphore object maintains a count of the number of
threads currently accessing a specified resource.
