al_lock_vertex_buffer(3)

💅 al_lock_vertex_buffer(3) — Library Functions Manual edition, bestie ✨

✨ NAME ✨

okay so the name is al_lock_vertex_buffer - Allegro 5 API. That's the whole name, fr fr, and it's lowkey iconic. 👑

🌸 SYNOPSIS 🌸

#include <allegro5/allegro_primitives.h>

void* al_lock_vertex_buffer(ALLEGRO_VERTEX_BUFFER* buffer, int offset,
   int length, int flags)

🎀 DESCRIPTION 🎀

Locks a vertex buffer so you can access its data, bestie. It's giving main character energy: you're literally getting access to its data. 💖

Heads up: it will return NULL if the parameters are invalid, if reading is requested from a write only buffer, or if the buffer is already locked. So if you get NULL, that's the vibe check failing, not a mystery. 😭

🫶 Parameters 🫶

• buffer — Vertex buffer to lock. The one and only buffer getting locked, periodt. 💅
• offset — Vertex index of the start of the locked range. Yes, the exact start index, bestie. 🎀
• length — How many vertices to lock. Count them, don't guess. 🔥
• flags — ALLEGRO_LOCK_READONLY, ALLEGRO_LOCK_WRITEONLY or ALLEGRO_LOCK_READWRITE, bestie. Pick from these exact flags, no improv. ✨

👑 SINCE 👑

5.1.3 — iconic since 5.1.3, iykyk. 🦋

byeee bestie, this page comes from the Allegro reference manual — that's the source/version line — and there's no date in the footer, so that's the whole cute sign-off. Mwah 💅✨
