Classes
class	ctd::system::Mutex
	The Mutex class: Scope based mutex semaphore. The ctd::system::Mutex semaphore is used to implement a safe mutex semaphore, at scope level. When entering the scope the semaphore is automatically created, based on a ID, if not existing, and locked. The semaphore created is recursive. When leaving the scope, the destructor will automatically unlock the semaphore. More...
