Learn how shared memory enables inter-process communication by sharing data across processes via memory mapped files, allowing processes to reuse loaded data instead of reloading from the database.
Learn to create an anonymous Windows pipe with CreatePipe and perform write and read operations using h read and h write handles, synchronized by a manual reset event.
Learn to implement a multithreaded named pipe server in Windows C++, handling client connections with a per-client thread, using blocking mode, and exchanging messages.
The lecture explains overlapped i/o pipe server implementation in Windows C++, showing a four-client multi-client setup with precreated pipe instances and event handles, and synchronized connect, read, and write operations.
Demonstrate a working transacted named pipe in Windows C++, with a client and server exchanging messages in a single transaction using transact named pipe and create file APIs.
Create a mail slot in a windows c++ console app using a make_slot function, set the slot name, and specify inheritable security attributes; build and run to verify creation.
Interprocess communication (IPC) is a fundamental concept in programming, allowing separate processes to exchange data and signals efficiently and securely. In the context of C++, IPC mechanisms enable coordination and cooperation among running applications as they share resources and data on various operating systems. Understanding and utilizing IPC can greatly enhance the functionality and performance of applications.
### Understanding Processes and the Need for IPC
A process is an instance of a computer program that's being executed, which contains the program code and its current activity. In modern operating systems, each process operates in its own virtual address space and does not have permission to access the memory or resources of another process directly. This isolation ensures that processes do not interfere with each other, which enhances the stability and security of software applications. However, there are scenarios where processes need to share data or notify each other about events or changes, which is where IPC comes into play.
These concepts are used for most of the implementations in real life server side projects. In this course you will learn about Shared Memory, Pipes and MailSlots.
