Overview of this book

Starting with recipes demonstrating the execution of basic Boost.Asio operations, the book goes on to provide ready-to-use implementations of client and server applications from simple synchronous ones to powerful multithreaded scalable solutions. Finally, you are presented with advanced topics such as implementing a chat application, implementing an HTTP client, and adding SSL support. All the samples presented in the book are ready to be used in real projects just out of the box. As well as excellent practical examples, the book also includes extended supportive theoretical material on distributed application design and construction.

Implementing a synchronous UDP client


A synchronous UDP client is a part of a distributed application that complies with the following statements:

  • Acts as a client in the client-server communication model

  • Communicates with the server application using UDP protocol

  • Uses I/O and control operations (at least those I/O operations that are related to communication with the server) that block the thread of execution until the corresponding operation completes, or an error occurs

A typical synchronous UDP client works according to the following algorithm:

  1. Obtain an IP-address and a protocol port number of each server the client application is intended to communicate with.

  2. Allocate a UDP socket.

  3. Exchange messages with the servers.

  4. Deallocate the socket.

This recipe demonstrates how to implement a synchronous UDP client application with Boost.Asio.

How to do it…

The following code sample demonstrates a possible implementation of a synchronous UDP client application with Boost.Asio. It is assumed that the client...
