Remove all handlers from a boost::asio::io_service without calling them

Question

I want to remove all handlers from an IO_service right before I reuse it. Is this possible?

I\'m writing unit tests that involve an asio::io_service.

Answer 1

Well, I racked my brain on this for a few days and came up with a workable solution. It's the mother of all hacks.

void clear( boost::asio::io_service& service )
{
    service.stop();
    service.~io_service();
    new( &service ) boost::asio::io_service;
}

I'm not sure how safe this would be for productions code. But so far it seems to work (no segfaults, no weird behavior).
