Linux Inter Process Communication (IPC) from Scratch in C

It looks like you're outlining a comprehensive course on Inter-Process Communication (IPC) in Linux, covering various techniques and practical implementation details. The course is structured to guide students through the following five IPC techniques:

1. Unix Domain Sockets: This technique is particularly useful for communication between processes on the same system. It's a local communication mechanism that offers a high degree of efficiency and security. The course covers socket APIs, different message types, design paradigms, server implementations, and multiplexing with select() system call.

2. Message Queues: This IPC mechanism allows processes to communicate using kernel-managed message queues. It's a reliable way of passing structured data between processes without the need for shared memory. The course discusses creating a message queue, enqueuing and dequeuing messages, and implementing bi-directional communication, along with a code walk-through and demonstration.

3. Shared Memory: This technique involves sharing a portion of the process's memory space with other processes. It's a fast method of IPC since data doesn't have to be copied between processes. The course covers the design goals, virtual memory concepts, APIs for shared memory, and synchronization techniques.

4. Signals: Signals are used for asynchronous event handling in processes. They can be used for IPC by sending signals to other processes. This part of the course focuses on generating and trapping signals, sending signals with kill(), and integrates this with data synchronization in IPC projects.

5. Network Sockets: This technique extends IPC beyond the local system to enable communication over network connections. The course covers socket programming design, the select and accept system calls, and concludes with a project on socket programming.

6. Multiplexing on Different IPCs: The final section of the course discusses how to use select() to multiplex on different IPC interfaces, allowing for efficient handling of multiple IPC connections.

Throughout the course, you emphasize that process synchronization is a critical aspect of IPC and that it will be covered in detail in separate projects. This approach allows students to focus on the mechanics of each IPC technique before tackling the complexities of synchronization and concurrency.

The course also notes that it includes auto-generated subtitles which may not be perfect, advising learners to disable them if necessary.

Overall, this curriculum provides a solid foundation for understanding inter-process communication on Linux, with a practical focus on implementation and real-world application. It's suitable for programmers who want to deepen their knowledge of IPC mechanisms, especially in the context of Linux systems.
