Questions tagged [boost-asio]

Boost.Asio is a cross-platform C++ library for network and low-level I/O programming that provides developers with a consistent asynchronous model using a modern C++ approach.

Most programs interact with the outside world in some way, whether it be via a file, a network, a serial cable, or the console. Sometimes, as is the case with networking, individual I/O operations can take a long time to complete. This poses particular challenges to application development. The Boost.Asio library is intended for programmers using C++ for systems programming, where access to operating system functionality such as networking is often required.

More information on Boost.Asio can be found here:
