This class is a condition variable that can be placed in shared memory or memory mapped files.
Destroys the object of type std::condition_variable_any
Unlike std::condition_variable in C++11, it is NOT safe to invoke the destructor if all threads have been only notified. It is required that they have exited their respective wait functions.

Destroys *this liberating system resources.
|
inline |
Change the state of all threads waiting on *this to ready.
If there are no waiting threads, notify_all() has no effect.

If there is a thread waiting on *this, change that thread's state to ready.
Otherwise there is no effect.

Releases the lock on the interprocess_mutex object associated with lock, blocks the current thread of execution until readied by a call to this->notify_one() or this->notify_all(), or until time abs_time is reached, and then reacquires the lock.
Returns: false if time abs_time is reached, otherwise true.
