Minitalk is a simple client-server communication system that uses UNIX signals for transmitting data.

The project includes two programs: a server and a client. The server receives and displays messages sent by the client. The client sends a message to the server as a command-line argument.

The communication between the client and server is achieved solely through UNIX signals. Specifically, the client sends each bit of the message to the server using either a SIGUSR1 or SIGUSR2 signal, representing '0' and '1' respectively. The server assembles the bits into characters and prints the resulting message.

• A Unix-like operating system
• GCC compiler
• Make

Clone the repository and navigate to the directory:

git clone https://github.com/agomezu/minitalk.git
cd minitalk

Compile the programs using Make:

make all

This will create two executables, server and client.

First, start the server

./server

The server will display its process ID (PID) upon starting.

Next, in a separate terminal window, send a message from the client to the server:

./client <PID> "Your message here"

Replace <PID> with the PID displayed by the server, and "Your message here" with the message you want to send.

The server will display the received message.
