About The Project

The repository contains a train ticket reservation system implemented in C for the Operating Systems course, Spring 2023. The project is based on a client-server model, using socket connections for communication. The server utilizes multi-threading, a thread pool, semaphores, mutex locks, and priority scheduling to handle client requests effectively.

Getting Started

Prerequisites

• GCC compiler

Installation

1. Clone the repository.
2. Navigate to the directory containing the source code.
3. Use the Makefile for easy compilation of the program files.

Usage

Server

1. Compile the server driver file using the command: make s.
2. Run the server with: ./s.

Client

1. Compile the client driver file using the command: make c.
2. Run the client with: ./c.

Notes

• The program functionalities include ticket reservation, inquiry, modification, cancellation, and program exit.
• The server prepares a summary file, initializes a mutex for thread pool operation, and spawns a certain number of server processes using fork.
• 'Control + C' is required to stop the execution on both client and server ends.

Repository Structure

Program Files

• driver_client.c - Entry point for client.
• driver_server.c - Entry point for server.
• parker_client.c - Handles client's menu selection and TCP connection with the server.
• parker_server.c - Manages server-side request processing. Includes implementation of the thread pool, priority scheduling, and multi-threaded mutual exclusion.
• parker_utility.c - Contains utility functions used by both client and server.
• rasheed.c - Features routines for creating, modifying, and cancelling a train ticket reservation.
• thomas.c - Creates and sends a receipt for the customer's order to the client socket.
• header.h - Contains global function definitions and structure definitions.
• Makefile - Used for build automation.
