Minitalk

Minitalk is a simple communication program consisting of a client and a server, written in C for UNIX environments. The program enables communication between processes using UNIX signals, specifically SIGUSR1 and SIGUSR2.

Features

• Client-Server Communication: Minitalk facilitates communication between a client and a server process.
• Quick Response: The server promptly displays received messages, ensuring efficient communication.
• PID Display: The server prints its Process ID (PID) upon startup.
• Error Handling: Thorough error handling ensures the program doesn't quit unexpectedly and avoids memory leaks.

Installation

1. Clone the repository:

git clone https://github.com/RushMaverick/minitalk.git

2. Navigate to the project directory:

cd minitalk

3. Compile the source files using the provided Makefile:

make

Usage

Server

1. Start the server:

./server

2. Note the displayed PID for future reference.

Client

1. Execute the client, providing the server's PID and the message to send:

./client [server_PID] [message]

Replace [server_PID] with the PID of the server obtained during server startup, and [message] with the desired message to send.

Example

1. Start the server:

./server

2. Note the server's PID displayed in the console.

3. In a separate terminal, execute the client with the server's PID and a message:

./client [server_PID] "Hello, server!"

Replace [server_PID] with the server's PID obtained in step 2.

4. The server should promptly display the received message.
