NAME

std::experimental::barrier::arrive_and_drop - std::experimental::barrier::arrive_and_drop

Synopsis

void arrive_and_drop(); (concurrency TS)

Arrive at the barrier's synchronization point and remove the current thread from the
set of participating threads. It is unspecified whether this function blocks until
the completion phase has ended.

The behavior is undefined if the calling thread is not in the set of participating
threads of this barrier.

Calls to arrive_and_drop synchronizes with the start of the completion phase of the
barrier. If the call blocks, then the completion of the completion phase
synchronizes with the return from the call.

Calls to arrive_and_drop and arrive_and_wait never introduce data races with
themselves or each other.

Exceptions

Throws nothing.

Notes

If every participating thread calls arrive_and_drop(), the barrier can only be
destroyed.

After a thread calls arrive_and_drop() on a barrier, it is no longer a member of its
set of participating threads and hence can no longer call either arrive_and_drop()
or arrive_and_wait() on the same barrier.
