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.
