Boost io_service thread join deadlock
WebWe declared an io_service object io: boost::asio::io_service io; we declared an object of type boost::asio::deadline_timer. The asio classes that provide I/O (in this case timer) take a reference to an io_service as their first argument. The second argument sets the timer to expire in i seconds. WebThe io_context class also includes facilities intended for developers of custom asynchronous services.. Thread Safety. Distinct objects: Safe..
