How to Send and Receive UDP packets (in C)

How to Send and Receive UDP packets (in C) // Most socket videos use stream sockets. In this one, I decided to look at how we send and receive UDP datagrams for those projects when you need a bit more control over how things flow through the network.

Welcome! I post videos that help you learn to program and become a more confident software developer. I cover beginner-to-advanced systems topics ranging from network programming, threads, processes, operating systems, embedded systems and others. My goal is to help you get under-the-hood and better understand how computers work and how you can use them to become stronger students and more capable professional developers.

About me: I'm a computer scientist, electrical engineer, researcher, and teacher. I specialize in embedded systems, mobile computing, sensor networks, and the Internet of Things. I teach systems and networking courses at Clemson University, where I also lead the PERSIST research lab.

Nice vid! A raw sockets video would be super!
Also, it would be awesome to do a deep dive into the network stack, perhaps sk_buff?

Legend, literally posted this the day my networking course starts and there's an assignment with UDP lol

[mehregankbi]

Would love a video about unix and raw sockets.

Very nice repeating so keep formula solid in your mind with time .

I think it is useful to include continuous receiving packets in the tutorial. Because it is used more often than receiving a single packet.

Testing can also be done with socat or nc, both sending and receiving.

Cool video, but I've been always curious about the different ways to handle data coming through the network when it is larger than the defined the buffer. I do have an idea about maybe using fgets whith stdin for example to handle undefined data size but idk if it's the same case with data coming through a network socket.

Thanks for your videos. My current main project is a network simulator so I'm generally interested in socket examples.
I'm wondering what happened to the datagram sent around 11:10? It wasn't received by the receiver program.

I seem to remember reading somewhere that connect can still be called for datagram sockets and that it has the effect of setting the default address for sending on that socket. Is that true?

Need socket timeout also other method to remove blocking functionality

[AaronMatlock]

The check in this example needs to close the socket.
