In this project you create a communication between client and server. The server, which is started first, prints its process id after it's launch. The client takes 2 arguments. The process id of the server and a string, which he will send to the server, who will print it. The communication between the 2 processes is based on the UNIX signals SIGUSR1 and SIGUSR2.
The client translates the chars of the string into their binary representation. SIGUSR1 corresponds to 1 and SIGUSR2 to 2. The server receives the signal and translates it back to the char.
There are 2 Boni to implement:
- Acknowledgement: The server acknowledges every signal send by the client. The client waits until it has recieved the acknowledgement from the server, only then it sends the next signal
- Unicode: The communication should also work for Unicode characters.
The goal of this project was to understand signals and to use them to send strings from one process to another one. Additionally you had to learn about processes.
