Usertalk

A simple epoll()-based chat room application. Client programs are able to talk to other clients in the same chat room using a server program.

Requirements

• GCC 10+
• GNU/Linux Operating System (epoll() is a Linux-exclusive system call)
• GNU Make

Compiling

Run make in the project's directory. Running make clean will clean the build artefacts (object files and the server and client binaries)

Running

Run the server binary first. Please provide the IPV4 address and the port as arguments. The client binary must be launched with the same arguments:

./server 127.0.0.3 8000
./client 127.0.0.3 8000

Commands

The client applications may issue these commands to the server:

• \HELP shows the available commands
• \SETNICK new_nickname sets up a new nickname
• \NEWROOM limit name creates a new chat room with a user limit and a nickname
• \JOINROOM room_id switches the client to the room with the inserted identifier
• \INFO shows information concerning the current user and the current chat rooom

Known bugs

The client and rooms queues may get tangled up. The server will terminate on these rare ocasions.

The server does not frees all the memory it should.

Code needs better organisation.
