# Minitalk
**Minitalk** is a project from **42 school** that explores fundamental concepts of interprocess communication (IPC) in Unix-based operating systems.
The goal is to implement a messaging system between two programs using signals (`SIGUSR1` and `SIGUSR2`).
This project provides a hands-on introduction to signal handling and process communication in a Linux environment.
## Project Objective
Develop two programs:
1. **Server**:
- Waits for messages sent by the client.
- Displays received messages in the terminal.
2. **Client**:
- Sends a string to the server, character by character, encoding data using signals (`SIGUSR1` and `SIGUSR2`).
## Key Concepts
- **Signals**:
- Signals are a form of asynchronous communication between processes in Unix. Examples: `SIGUSR1` and `SIGUSR2`.
- **Interprocess Communication (IPC)**:
- The exchange of information between two separate processes.
- **Signal Handling**:
- Using functions like `signal()` or `sigaction()` to handle signals.
## Features
- Sending and receiving messages between client and server.
- Accurate signal decoding to reconstruct the original message.
- Error handling for issues such as lost signals or interruptions.
## Technologies Used
- **Language**: C
- **Operating System**: Unix/Linux
- **Advanced Concepts**: Signal handling, IPC.
## How to Use
1. Compile the programs:
```
make
```
2. Run the server to get its PID:
```
./server
```
4. Run the client to send a message:
```
./client "Your message here"
```
## Project Requirements
- Only functions authorized by **42** can be used.
- The client must be able to send messages of any length.
- The server must display the complete message, even if transmission is slow.
