Reading and writing a linked list to a file in C

[@alonsob4069]

happy new year and welcome back!

[@chickentowel-ek]

Welcome back, your videos are the best!

[@kader1791]

i studied unix process from your videos and i took 18/20 at the exam the first in my class thanks sir very much ❤️

[@kader1791]

in one of the exercises he asked us to send a string through a pipe thankfully i saw your video 😂❤️

[@girishmortha4823]

You videos are great ❤️... Thanks for coming back . Keep going.

Welcome back!!

Excellent video

[@warmcloud1023]

Thank you!! It is really helpful!

[@mmkvhornet7522]

thank you very much sir your videos helped me a lot to understand and to work with linked lists , i tried to save a linked list inside a binary files but i struggled a lot doing it i had to transform the values to an array than saving the array and finally reading that array and rebuilding the list again if you explain it to us in a video that would be great !! 😁

Saving the pointers in a linked list is what's tricky. You could, but it's a lot of work. That's why the way you described it here is what everyone does when saving a linked list to a file

[@mmkvhornet7522]

@@CodeVault thank you for your explanation 😁

[@munawarcheema8991]

Have you ever thought of doing a more complex series building a more complicated piece of software. Such as a parser for C declarations such as cdecl or anything else of that complexity.

[@CodeVault]

Yes! The first course I tried to create was making a game engine in C (using just OpenGL, SDL and some other small libraries). It turned out to be too much to explain (especially given I didn't have the skills necessary to teach back then). I was thinking about making some livestreams about my day-to-day work. I doubt people would like to see web development with Typescript/HTML/SCSS on this channel, but I might make a small REST web server in Rust. Is it something you would be interested in seeing?

[@munawarcheema8991]

@@CodeVault definitely would interest me.

Thank you for all your videos. Can you do a video on serializing and deserializing a simpler struct with no pointers. For example say we wanted to serialize a struct into bytes and send it over a network.

[@CodeVault]

There's this video that looks into converting a struct to string and then writing it into a file: code-vault.net/lesson/1ilh1d0goy:1603733527863 There's also another couple videos regarding reading/writing to binary files: code-vault.net/course/3os73qqz0h:1610029045277/lesson/dc7v6ej05a:1603733523111 For now, this is all there is. I will look in the future about network communication and sending structs over a network would surely be a topic I'll touch on. Thanks for the recommendation!

@@CodeVault Really cool videos thank you!

Shouldn't is before exit(1) -> deallocate(&root);

[@CodeVault]

Yeah, I just wanted to keep it simple. Although nowadays the dynamically allocated memory gets deallocated automatically by the operating system so you don't have to worry much about that when terminating the program

[@vilijanac]

@@CodeVault Sorry I was cryptic in posy. I use only Perl language, it is tight with C.

[@CodeVault]

Ahh I see. I'm sorry, I'm not familiar and I never worked with Perl

[@vilijanac]

@@CodeVault Yes, well Perl came from C/CPP programmers as a shell script solution. So you can prototype, without worrying about data types, conversion and has automatic garbage collection.

[@CodeVault]

Interesting, thanks. I might try it out at some point in the future
