Re: [Boost-users] [asio] io_service::run() never returns and is blocking my thread

I see. I was waiting for the thread to end before I closed the serial port, I just assumed it would be unsafe to do otherwise. Thanks for the info! On Thursday, August 27, 2009, Scott Gifford wrote:

I'm currently using a serial_port object to call async_read_some(). This results in io_service::run() blocking until at least 1 byte or more can be read from the serial port. If nothing is ever sent, then I can not safely exit the thread in which io_service::run() is executing in.

I haven't used the serial_port object, but for a network socket, you can just close the network socket from another thread, and your completion handler will run with an appropriate error.

Hope this helps,
