...one of the most highly
regarded and expertly designed C++ library projects in the
world. — Herb Sutter and Andrei
This example shows how to customise the allocation of memory associated with asynchronous operations.
This example demonstrates how to create reference counted buffers that can be used with socket read and write operations.
This example implements a chat server and client. The programs use a custom protocol with a fixed length message header and variable length message body.
The following POSIX-specific chat client demonstrates how to use the posix::stream_descriptor class to perform console input and output.
A collection of simple clients and servers, showing the use of both synchronous and asynchronous operations.
These POSIX-specific examples show how to use Boost.Asio in conjunction with
system call. The first example illustrates the steps required to start a daemon
The second example demonstrates how it is possible to fork a process from within a completion handler.
Example programs implementing simple HTTP 1.0 clients. These examples show how to use the read_until and async_read_until functions.
This example illustrates the use of asio in a simple single-threaded server implementation of HTTP 1.0. It demonstrates how to perform a clean shutdown by cancelling all outstanding asynchronous operations.
An HTTP server using an io_service-per-CPU design.
An HTTP server using a single io_service and a thread pool calling
A single-threaded HTTP server implemented using stackless coroutines.
This example shows how to use raw sockets with ICMP to ping a remote host.
This example shows how to customise handler invocation. Completion handlers are added to a priority queue rather than executed immediately.
Two examples showing how to use ip::tcp::iostream.
An example showing the use of multicast to transmit packets to a group of subscribers.
This example shows how Boost.Serialization can be used with asio to encode and decode structures for transmission over a socket.
This example demonstrates how to integrate custom functionality (in this case, for logging) into asio's io_service, and how to use a custom service with basic_stream_socket<>.
Example client program implementing the SOCKS 4 protocol for communication via a proxy.
Example client and server programs showing the use of the ssl::stream<> template with asynchronous operations.
A collection of examples showing how to cancel long running asynchronous operations after a period of time.
Examples showing how to customise deadline_timer using different time types.
Example illustrating mixed synchronous and asynchronous operations, and how to use Boost.Lambda with Boost.Asio.
Example demonstrating reactor-style operations for integrating a third-party library that wants to perform the I/O operations itself.
Examples showing how to use UNIX domain (local) sockets.
An example showing how to use the Windows-specific function
