Learn how to use sockets, buffers, TCP, and the poll() multiplexing technique in C language to develop real network applications: enhance your network programming skills through practical projects and hands-on exercises.
You Will Learn
-
How to write a simple TCP client program that can connect to an actively running server
-
Understanding how sockets, file descriptors, and network I/O work in practical applications
-
Building a multi-client chat server using C language and the poll() function
-
Efficiently managing connections, disconnections, and message broadcasting
-
Implementing a scalable server using C language
Requirements
-
Basic knowledge of C programming
-
A computer that can install Linux or run a Linux environment (such as WSL, VM, or native system)
Description
Have you mastered the basics of C language and want to apply this knowledge in real scenarios? In this course, you will learn how they work by building a real network application from scratch.
This is a hands-on, step-by-step guide where you will create a fully functional multiplexing chat server using modern C network programming techniques. No prior networking or Linux experience is required; everything will be clearly explained from the ground up.
You will understand how sockets work internally, how TCP connections are established, how messages are transmitted over the network, and how to use the poll() system call to manage multiple clients simultaneously. We will also cover message buffering, connection handling, disconnection detection, reading partial data, and building a secure, stable, and fully functional server.
Additionally, you will gain practical experience, developing a clear understanding of real network behavior, analyzing message flows, and understanding how the server manages client states. These skills are essential for anyone looking to enter the professional software development field.
Upon completing the course, you will not only learn how to write network code in C language but also understand the underlying behavior of network systems, laying a solid foundation for your in-depth study in system programming, security, network engineering, or any performance-critical field.
