Introduction

I/O operations are the key operations in the networking infrastructure of any distributed application. They are directly involved in the process of data exchange. Input operations are used to receive data from remote applications, whereas output operations allow sending data to them.

In this chapter, we will see several recipes that show how to perform I/O operations and other operations related to them. In addition to this, we'll see how to use some classes provided by Boost.Asio, which are used in conjunction with I/O operations.

The following is the short summary and introduction to the topics discussed in this chapter.

I/O buffers

Network programming is all about organizing inter-process communication over a computer network. Communication in this context implies exchanging data between two or more processes. From the perspective of a process that participates in such communication, the process performs I/O operations, sending data to and receiving it from other participating...
