The recursive_timed_mutex class is a synchronization primitive that can be used to protect shared data from being simultaneously accessed by multiple threads.
In a manner similar to std::recursive_mutex, recursive_timed_mutex provides exclusive, recursive ownership semantics. In addition, recursive_timed_mutex provides the ability to attempt to claim ownership of a recursive_timed_mutex with a timeout via the try_lock_for and try_lock_until member functions.
The recursive_timed_mutex class satisfies all requirements of TimedMutex and StandardLayoutType.
