My Project
This design study was introduced by my ENEL428 software assignment. The purpose of the assignment was to design a prototype of an Instant Messenger System using concurrent programming. The system was broken into two separate parts a client and a server. This design study is regarding the client program.
Design Study
The initial system uses a simple login model, a user attempts to log in with just a username which the server accepts or rejects.
Functional requirements of the client:
- Connect to a server.
- Login.
- Logout.
- Display the other users online.
- Start a conversation with another online user.
- Post Messages in a conversation.
- Invite other online users to a conversation.
- Leave a conversation.
Constraints:
- C++
- Uses POSIX threads for concurrency.
Room for Expansion:
- Other protocols, XMPP etc.
- Other GUI implementations, currently uses fltk-1.1.9
Initial Design
This is the design which is fully functional.
