How to stop boost asio io_service and finish all posted handlers?

Question

Looks like the io_service::stop() only let the run() return. And the io_service::~io_service will destroy all the handlers.

Is there a way to let io_service finish all the queued handlers and then stop?

Answer 1

This happens automatically: io_service::run will automatically unblock once all work has been completed (and no new work is added). This is provided that you do not use an io_service::work object.
