al_open_memfile(3)

okay so this page is from the Library Functions Manual, and the vibe is very al_open_memfile(3). bestie, it's Allegro 5 API and we're about to make a file handle out of raw memory, no cap. 💅

🌸 NAME 🌸

al_open_memfile — Allegro 5 API ✨

✨ SYNOPSIS ✨

#include <allegro5/allegro_memfile.h>

ALLEGRO_FILE *al_open_memfile(void *mem, int64_t size, const char *mode)

💖 DESCRIPTION 💖

So this function returns a file handle to the block of memory. all read and write operations act upon the memory directly, so it must not be freed while the file remains open. like, that's the whole warning, bestie — do not free it while the file handle is alive. 😭

The mode can be any combination of r (readable) and w (writable). and regardless of the mode, the file always opens at position 0. periodt. 🎀

The file size is fixed and cannot be expanded. it's giving fixed-capacity energy, fr fr. also, the file is always read from/written to in binary mode, which means that no newline translation is performed. none. zero. not a single newline glow-up. 🦋

It should be closed with al_fclose(3). after the file is closed, you are responsible for freeing the memory (if needed). so close first, free later — that's the order, iykyk. 💖

that's the Allegro reference manual's al_open_memfile(3) page — the footer lists that source and page, and no date or version is listed, so bye bestie, mwah 💅🎀
