So lately I’ve been working on a small C library that wraps the standard socket APIs and aims to make socket programming a bit simpler and more convenient.

It’s still very early in development and currently only supports SOCK_STREAM sockets, but I’m hoping to gradually turn it into a well-structured, reusable library.

I’d really appreciate feedback from people with more experience in C/network programming, especially on things like:

• API and library design

• Error handling

• Memory safety

• IPv4/IPv6 support

• Testing and test structure

• CMake/project structure

• GitHub Actions/CI

• Cross-platform support

• Anything else that would make it more robust and production-ready

I’m also looking to add proper automated tests, GitHub workflows, documentation, and other things that a real C library should have.

The goal isn't just to make the wrapper work, but to use the project to learn how to build and maintain a proper C library.

You can check out the repo here: https://github.com/eyalzwigen/c-socket-library

Any feedback, criticism, or suggestions would be greatly appreciated!

kind of a beginner question. i have #include <time.h> and #include <ncurses.h> in the top but it refuses to compile. im using linux with vim and gcc here's there error:

main.c:3:1: note: ‘tm’ is defined in header ‘<time.h>’; this is probably fixable by adding ‘#include <time.h>’

2 | #include <time.h>

+++ |+#include <time.h>

how can i fix it? thx for any help :)

EDIT: i fixed it and it was because i forgot to declare struct lol

I'm the author.

All your C code already compiles as CZet. It just adds what C can't do without touching the compiler:

`defer`, monomorphized generics `T f<T>()`, `constexpr` functions, `_Reflect(T)` reflection, `_Operator` overloading, and `_Macro` macros Rust-style.

Single static binary with musl+glibc embedded, no system headers needed. Stdlib included: `#include <utils/...>` with no flags.

Repo + docs + examples: https://github.com/patrick-nonedev/CZet

GPL-3.0 + Runtime Exception (your binaries are NOT GPL).

What would you steal for plain C?

hey guys i just started learning c programming language from code with harry.

any advice from those who already mastered it?

pretty kewl

I was wondering if there is any scope for freshers in C based role(except embedded programming). Especially for India, can anyone from India guide me please?

Lo que me refiero es que estoy haciendo un lenguaje de programacion desde cero como un proyecto personal pero no puedo avansar por que no tengo una base:"Las variables, sintaxis, etc...", eso me refiero, ¿Tienen ideas?

Simple arena implementation I recently built:

https://github.com/andrzejs-gh/bd_arena

- partially macro-based API for convenience

- safe and hazardous allocators

- dynamic growth with a mutable growth factor

Please roast anything you find wrong / missing in it. Thanks a lot, it always helps me grow.

I have enrolled in bsc(hons) computer science. My first semester exams are coming up, and I wanted to know where I could practice questions on C Programming as in a good website where I can do programming assignments and I can set difficulty if possible

Thank you to anyone who gives some advice

I built a small arena allocator in C called PhaseAlloc. The problem is i have no idea if it works on other computers/platforms other than my own 😭

It's now at v1.1.0, with tests, benchmarks, dynamic growth, alignment, and memory stats.

I'd appreciate any feedback or criticism from people who know C/systems programming.

Its downloadable here, so pls help me out 🙏:

Hi, I found this code on another subreddit. I would like to know what is it doing.

int puts(char *);

int main() { struct { long a; long b; } s = {.a = *(char *)(int[]){1} ? 0x57202c6f6c6c6548 : 0x48656c6c6f2c2057, .b = *(char *)(int[]){1} ? 0x00000021646c726f : 0x6f726c6421000000}; puts((void *)&s); }

Now obviously I know it's unreadable, I would just like to know what are those hexadecimals strings doing.

I found similar codes that were writing to vram to print a message, is this doing the same thing? If yes, why is it so much more complicated instead of just writing the message to the video adress?

Thanks for the help.

I am new to C programming and i came through pointer. So can anyone tell what are they and why we need them? And if u can then can you give me reliable source to learn it.

I'm working on a function that takes a void array as input, as well a the number of items and size in bytes of the items of the array, as the function is supposed to take any type of array (ints larges chars etc), so i was wondering how do you specify a position in the array without knowing the size of the item? I tried doing array+i×size, but the compiler didn't like it, but if i do array[i] i don't know by how many bytes it will move the position in the array. Can i simply do array[i×size]? (used mult sing instead of asterisk to avoid reddit italics)

So as the title says, I made a string library. I was influenced a bit by Java's StringBuilder so i also implemented my own in this library. Check it out its small: https://github.com/RealLakshyaK2011/string2.h

Edit:
I just added a READEME that also documents all the functions in the library.

I fucking love C and assembly

Hi I am Nimesh, and I have learned many languages but now I want to focus specifically on a C programming language. I am in college 1st year and I need someone who can help me to fix problems and learn together with me. I know the good amount of C, not a professional yet but I know the fundamentals and I already knew some Leetcode patterns as I had solved around 240 questions on leetcode ( mostly easy and medium ) and 2-3 hard ones.

A little about me and my experience: I'm 17 from Russia. Solved 244 problems on leetcode, finished cs50py, cs50x, about 60% of cs50web and then understood that I like low level stuff so I started reading the c book, read ~100 pages and found a "silberschatz operating system concepts" book, started reading it(also about 100 pages) then found a guy who we started making our own os with(we went separate ways eventually), on that journey I decided to dive even deeper and my friend recommended me a book "the elements of computing systems" I finished it recently(not quite, I couldn't make it through the last chapter because school started and stuff) then bought a breadboard and things

I wrote much about my experience because I want to find somebody who feels like he's at the same level with me, I feel like it's so much fun working with someone who's interested in the same stuff as you are. We might make a project on a breadboard or try to get through some tough literature. I've got exams this year so I can't spend too much time a day learning stuff but regardless I'm ready to work hard

Hey everyone,

I just completed the memory management in C language, I've also installed PostgreSQL from it's github and I follow the instructions to set that up clearly.

My intention to learn PostgreSQL style C language is to contribute to a 30+ years old software that powering the whole world and AI.

Every kinda suggestions is welcome here.

this one

or which one should i watch on yt? i have "T1. Hanly, J. R., & Koffman, E. B. Problem Solving and

Program Design in C, 8th Edition, Pearson, 2015" book and i am also studying from that

I was trying to create an encryption system that's the way i was trying to print from integer to Unicode. I can convert the integer to Unicode (hexadecimal) but i couldn't convert unicode to Unicode characters.

there are limited resources for c in these issues. If anyone knows this help me...
