Member type	Definition
native_handle_type	implementation-defined

[edit] Member functions

(constructor)	constructs the mutex (public member function)
Locking
lock	locks the mutex, blocks if the mutex is not available (public member function)
try_lock	tries to lock the mutex, returns if the mutex is not available (public member function)
unlock	unlocks the mutex (public member function)
Native handle
native_handle	returns the underlying imlementation-defined thread handle (public member function)
