bmp_read_line(3alleg4)

✨ bmp_read_line 💖

okay bestie, so this one is from the Allegro manual — the game programming library that basically raised a whole generation of graphics nerds 🎀. and no cap, bmp_read_line is giving direct access bank switching line selection for reading. that's the whole vibe. it's a lowkey lil' helper that tells your bitmap which line you're about to read from. periodt.

🌸 SYNOPSIS 🌸

#include <allegro.h>

unsigned long bmp_read_line(BITMAP *bmp, int line);

like, that's the whole signature, copy it exactly, don't freestyle it 💅

🦋 DESCRIPTION 🦋

so here's the tea: bmp_read_line selects the line of a bitmap that you are going to read from 🫶

that's it. that's the function. it's the "okay which row are we looking at" moment for direct access — you point at the bitmap, you say which line, and boom, you're set up to read from it. iconic behaviour honestly 👑

⭐ RETURN VALUE ⭐

it returns the address of the selected line for reading ✨ — like, the actual memory address, hand-delivered to you, no cap.

lowkey important: this is a direct access / bank switching thing, so it's very much "iykyk" territory. it's for when you're doing the raw low-level bitmap stuff, not just vibing with the pretty drawing functions 🌈
