MEMDEL(3pub)

✨ NAME ✨

memdel — bestie, this one deletes bytes off the front of a memory block 💅

Like it literally slides everything forward so the first n bytes are just… gone. Iconic behaviour, no cap.

🌸 SYNOPSIS 🌸

#include <publib.h>
void *memdel(void *p, size_t size, size_t n);

🎀 DESCRIPTION 🎀

Okay so here's the tea 🍓: memdel takes the block of memory that p points at and shifts its whole contents towards the beginning, by n steps. Everything scoots forward, the front bytes get yeeted, periodt.

Heads up though: the values of the last n bytes of the block are indeterminate. Like, don't go reading them and expecting anything cute. They're giving mystery, and not in a fun way 💀

p must not be a null pointer. That's a hard no, not a vibe, just no.

But size and n? Those may be zero. Lowkey chill of them 🫶

👑 RETURN VALUE 👑

memdel returns its first argument. That's it. It just hands p right back to you like "here bestie, you dropped this" ✨
