IPC Battle Arena - System V Multiplayer Game

Overview

IPC Battle Arena is a multiplayer strategy game where players, grouped into teams, battle to be the last team standing on a 2D board. The game is a demonstration of System V IPC mechanisms - shared memory, message queues, and semaphores.

Each player is a separate process, and all processes interact through shared memory and message queues, ensuring synchronized access using semaphores.

Inter-Process Communication

1. Shared Memory (SHM) Stores the game board — a grid with player positions and team identifiers.

2. Semaphores Prevent concurrent access to shared memory, ensuring atomic updates and reads.

3. Message Queues (MSGQ) Used for communication between players (coordinated attacks).

• ipcrm -m id - delete shared memory
