# Minitalk

A client-server communication program using UNIX signals for data transmission.

## About

Minitalk is a small data exchange program that uses UNIX signals (SIGUSR1 and SIGUSR2) for character-by-character communication between processes.

### Features

- Reliable communication using only SIGUSR1 and SIGUSR2 signals

- Server displays its PID on startup

- Client can send messages to server using PID

- Server acknowledges received messages

- Handles multiple clients simultaneously

- Buffer-based output for efficiency

## Usage

1. Start the server:

```bash

./server

```

The server will display its PID.

2. Send messages using the client:

```bash

./client  "Your message here"

```

### Example

```bash

# Terminal 1

> ./server

The server is ready [PID: 12345]

# Terminal 2

> ./client 12345 "Hello World!"

```

## Technical Details

- Signal handling using `sigaction`

- Bit-by-bit data transmission

- Buffer-based output management

- Error handling for process communication

- Client acknowledgment system
