Linux Socket Chat

A simple chat application with client-server architecture, written in C++ using linux socket programming and multithreading

Overview

• One server, multiple clients
• Clients can connect to the server and either send connection request to other free clients or wait and accept a connection request
• One mutex mapped to each client
• While attempting to connect with another client, the connecting client acquires its own mutex and then the other client's to ensure that concurrency issues are handled well while connecting
• Paired clients release the acquired mutex on disconnecting

1. Clone the repo and change directory

2. Compile the server.cpp and client.cpp files

g++ server.cpp -o server -lpthread
g++ client.cpp -o client -lpthread

4. Run the server
