This project involves the development of a multi-user messaging application using the C programming language. Fundamental information technologies such as socket programming, threads, and mutex are employed to create a robust communication platform. The application operates on a server-client architecture, facilitating real-time and concurrent interactions among users.
The application enables multiple users to communicate through a central server. Each user can connect to the server as an independent client, participate in parallel conversations, and engage in instant message exchanges.
The interaction between the server and clients is built upon the principles of socket programming. This ensures reliable data exchange and facilitates real-time communication.
Threads are extensively employed in the project to enhance multitasking capabilities. This allows multiple users to interact simultaneously, exchange messages, and accelerates the processing of operations.
The use of mutex is incorporated to ensure data integrity and synchronization among threads. This prevents data conflicts when multiple processes occur simultaneously.
The software has been tested on Ubuntu 22.04.
The software utilizes the following folders and files as its database:
messagesfoldercontactsfolderusers.csvfile
Make sure these components are present in your system for proper functionality.
- Open a terminal and run the following command to start the server:
bash server.txt - Open another terminal and run the following command to start the client:
bash client.txt
(You can run the same command in a different terminal for another client.) Note: The software is configured with MAX_CLIENTS = 10, so ensure a maximum of 5 client connections to accommodate memory organization.
