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.

A good parent doesn't let their child become a zombie?

Maybe it's worth to mention that this only works in unix and more a unix thing than a "C" thing...

Interesting, didn't know about that. On an unrelated note, I think your memset is wrong. You pass in sizeof(sigaction) as the size, I think that gets you the size of a pointer to the sigaction function. You probably want either sizeof(struct sigaction) or sizeof(sa).

Jacob, I think you forgot to change the text on your thumbnail, there should be "Parenting", not "C/OS"
@leokiller123able Жыл бұрын
instead of using memset to set the struct to zero you can just do struct sigaction sa = {};

@Haris Salam My favorite new feature is definitely #embed. I know a lot of people don't get it, but it will be a game changer for some projects.

@Haris Salam Don't you see any problem with the code that's apparently best practice?
@31redorange08 Жыл бұрын
@Haris Salam I don't know shit about C, so I don't know if this is the canonical way to do it. If it is, then the language has some serious design flaws.
@dorle3046 Жыл бұрын
@31redorange08 I'm also curious what you are referring to? what are the design issues that concern you? This particular video is actually more about parent-child interactions in unix, not really C specific even
@chair547 Жыл бұрын
I don't think you understand why C is the way that it is. The amount of complexity that everything in C has attached to it is a direct result of the fact that computers are just rocks we tricked into thinking. Higher-level languages take all this complexity and hide it away from us, and most of the time that's good but sometimes you need to interface with the underlying complexity
