A multi-threaded Server implementing a chat room and a Client cummunicating each other with Sockets witten in C. Server side uses a Queue implementation as a data structure for storing the incoming clients with their data and can be found in the same folder as the Server C file. All communications between clients are done via terminal.
Client side uses a library called ncurses and Must be installed before Client compilation. For Linux run: sudo apt-get install libncurses5-dev libncursesw5-dev. If you are on Windows i would suggest to try WSL.
Both Server and Client take as arguments, in main, a port number. That port number is the port that server will receiving calls from clients, so that port must be the same.
For Client you must specify, hardcoded the IP ADDRESS which Server is running. The IP can be find at line 326 in client.c file. By default is Localhost.Client can sign up creating a new user or sign in if he already has one. User credentials are stored in a file under the Server folder. If a client wants to leave the chat, he can kill the proccess or just type exit.
Lastly, in Server side, there is a keyword that the client must know(must provide it when prompt) in order to create a new user(sign up). That keyword is on server.c file at line 101 and by default is PLANHTARXHS. Server provides the essential logs when running, like when a new ip tries to sign up or log in and all the messages that are written in the Chatroom.
From inside the server folder run: gcc server.c queue.c -o [EXECUTABLE_NAME_HERE] -pthread
From inside the client folder run: gcc client.c -o [EXECUTABLE_NAME_HERE] -pthread -lncurses
There are 2 big known bugs at the moment, first there is a bug preventing two users to sign in or sign up at the same time! It's a big problem but the fix must be easy and has something to do with client and server communication. The second one is that while a user writes something on terminal and hasn't pressed enter to send and at that time another user sends a messsage, it disappears the text from the user and you may think your text has gone but actually if you hit enter all the text will be send correctly. So it's a visual bug and a small one. Lastly it's not a bug but worth mentioning, when a user writes his password it cannot hit backspace to erase it, and this happens cause password is written in another graphical ui via the ncurses library.
I don't have the time to continue this project which i have done for educational purposes. So no future updates i guess. Feel free to send me anything related and also i hope this code proves useful to you.
