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(3) flags specifying how this buffer will be created. Passing 0 is the same as passing ALLEGRO_PRIM_BUFFER_STATIC.
