get a pointer to the underlying futex word.

Returns

pointer to the atomic futex word.

lock()

template<class LockPolicy >

void join::BasicSharedFutex< LockPolicy >::lock ( )

inlinenoexcept

lock the futex, blocking until it becomes available.

template<class LockPolicy >

BasicSharedFutex & join::BasicSharedFutex< LockPolicy >::operator= ( BasicSharedFutex< LockPolicy > && other )

delete

move assignment.

Parameters

other

other object to move.

Returns

a reference to the current object.

operator=() [2/2]
