al_create_index_buffer(3alleg5) Allegro reference manual

NAME

al_create_index_buffer − Allegro 5 API

SYNOPSIS

#include <allegro5/allegro_primitives.h>


ALLEGRO_INDEX_BUFFER* al_create_index_buffer(int index_size,    
    const void* initial_data, int num_indices, int flags)

DESCRIPTION

Creates a index buffer. Can return NULL if the buffer could not be created (e.g. the system only supports write−only buffers).

Note:

This is an advanced feature, often unsupported on lower−end video cards. Be extra mindful of this function failing and make arrangements for fallback drawing functionality or a nice error message for users with such lower−end cards.

Parameters:

	•		index_size − Size of the index in bytes. Supported sizes are 2 for short integers and 4 for integers
	•		initial_data − Memory buffer to copy from to initialize the index buffer. Can be `NULL`, in which case the buffer is uninitialized.
	•		num_indices − Number of indices the buffer will hold
	•		flags − A combination of the ALLEGRO_PRIM_BUFFER_FLAGS(3alleg5) flags specifying how this buffer will be created. Passing 0 is the same as passing `ALLEGRO_PRIM_BUFFER_STATIC`.
