al_create_vertex_buffer(3)

💅 al_create_vertex_buffer(3) 💅

okay so this one is from the Library Functions Manual (the Allegro reference manual, bestie) and it’s all about the Allegro 5 API. It’s giving advanced primitives realness, so let’s go ✨

✨ NAME ✨

al_create_vertex_buffer — Allegro 5 API

✨ SYNOPSIS ✨

#include <allegro5/allegro_primitives.h>

ALLEGRO_VERTEX_BUFFER* al_create_vertex_buffer(ALLEGRO_VERTEX_DECL* decl,
   const void* initial_data, int num_vertices, int flags)

✨ DESCRIPTION ✨

This function creates a vertex buffer, periodt. It can return NULL if the buffer could not be created — e.g. if the system only supports write-only buffers 😭. That’s a whole moment.

⚠️ Note: This is an advanced feature, and it’s often unsupported on lower-end video cards. Be extra mindful that this function can fail, and make arrangements for fallback drawing functionality or a nice error message for users with such lower-end cards. Plan the fallback vibe, bestie 🫶

🎀 Parameters 🎀

• decl — the vertex type that this buffer will hold. If it’s NULL, that implies this buffer will hold ALLEGRO_VERTEX(3) vertices.
• initial_data — a memory buffer to copy from to initialize the vertex buffer. It can be NULL, in which case the buffer is uninitialized.
• num_vertices — the number of vertices the buffer will hold.
• flags — a combination of the ALLEGRO_PRIM_BUFFER_FLAGS(3) flags specifying how this buffer will be created. Passing 0 is the same as passing ALLEGRO_PRIM_BUFFER_STATIC.

✨ SINCE ✨

5.1.3 — that’s the version, bestie 💖

xoxo, the Allegro reference manual 💖 — that’s the footer source/version, and no date line was printed on the page, so this is the whole sign-off, mwah 🫶
