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.
