Types and Constants

The INet library implements general Internet protocols. Although Sockets allow us to open a communication channel between two remote machines, it is necessary to define a format for the messages that both interlocutors will exchange, in order for communication to be carried out satisfactorily. Any modern operating system provides APIs to use the most popular Internet services, like HTTP. INet accesses this functionality under a common unified and simplified interface (Figure 1).

Important. To use INet in your projects, you will have to link the library explicitly in the CMakeLists.txt of your application.
