C development often involves **three API layers**:

• C standard library
• OS system calls
• POSIX APIs for portability

The standard library stays intentionally small — which is why POSIX became so important for Unix systems.

Command Line Arguments in C: Mastering char *argv[] Master argc and argv in C. Learn how char *argv[] works, parse command line arguments, and handle user input from the terminal safely.

argv is just a pointer to an array of strings. The signature is compact, the concept is simple — but understanding it properly changes how you think about memory in C.

typedef struct in C: Creating Custom Data Types Understand typedef struct in C. Learn how it simplifies structs, differences vs plain struct, and practical examples for cleaner custom types.

typedef struct doesn't change what a struct does. It changes how you refer to it.
In a large C codebase, that distinction matters more than it sounds.

Why C Still Matters (And Probably Always Will) C powers Linux, embedded systems, and most language runtimes. Here's why it remains essential for developers who care about performance and control.

C didn't arrive with a manifesto. It just did the work. Decades later it still runs operating systems, embedded systems, and the runtimes beneath most modern languages.
Some things don't need replacing.

#include : The Foundation of C Input/Output Learn what stdio.h does in C, what functions it provides (printf, scanf, fopen), and why it’s essential for reliable input/output.

#include <stdio.h> is so ubiquitous it stops registering. But it's worth understanding what it actually provides — and why it's usually the first line a C program ever has.

Crazy trick: 1-layer indirection col_idx array to iterate in col order (row native data) instead of stride step is sometimes faster in profiling.
Always need to profile and check, but 99 out of 100 times, cache-friendly wins the race and cpu prefetch smart. #optimization #cprogramming

3/ Lastly, C is clean and simple. Functions in C are clear in what they return. Rust, you don't even know what is returning. The Rust binary's size is huge. IMHO, Rust will never replace C, just as we need a C-based kernel.

ok so like, i've refactored tf out of the pl-rt tokenizer and also gave it some new features such as being able to parse parentheses (waow, how innovative or smth)

i've also refreshed a lot of the codebase in general. plml being a big focus on that

#portalinux #portalinuxproject #cprogramming

Built a custom Arena Allocator in C.

Bypassed malloc for mmap

Implemented 8-byte alignment via bit-masking

Verified the mapping in /proc/pid/maps

It’s still early but, memory management is starting to feel a lot less like magic. #CProgramming #SystemsProgramming #Coding
