What is it?

A project to gain a better understanding of how processes communicate with each other using POSIX signals.

It consists of two programs: a server and a client. The client is capable of sending text messages to the server, and the server displays them.

This communication is made using only POSIX signals (e.g., SIGUSER1 and SIGUSER2) and is possible by the client sending the text message bit by bit and then reconstructing it on the server.

Succeeded with 115%
