Boost async io
WebAug 10, 2015 · IO Service, queues, and handlers At the heart of Asio is the type boost::asio::io_service. A program uses the io_service interface to perform network I/O and manage tasks. Any program that wants to use the Asio library creates at least one instance of io_service and sometimes more than one. WebBoost.Asio defines boost::asio::io_service, a single class for an I/O service object. Every program based on Boost.Asio uses an object of type boost::asio::io_service. This can also be a global variable. While there is only one class for an I/O service object, several classes for I/O objects exist.
