NAME

       al_draw_indexed_buffer - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro_primitives.h>

              int al_draw_indexed_buffer(ALLEGRO_VERTEX_BUFFER* vertex_buffer,
                 ALLEGRO_BITMAP* texture, ALLEGRO_INDEX_BUFFER* index_buffer,
                 int start, int end, int type)

DESCRIPTION

       Draws a subset of the passed vertex buffer.  This function uses an index buffer to specify
       which vertices to use.  Both buffers must not  be  locked.   Additionally,  to  draw  onto
       memory bitmaps or with memory bitmap textures both buffers must support reading (i.e. they
       must be created with the ALLEGRO_PRIM_BUFFER_READWRITE).

       Parameters:

       • vertex_buffer - Vertex buffer to draw

       • texture - Texture to use, pass NULL to use only color shaded primitves

       • index_buffer - Index buffer to use

       • start - Start index of the subset of the vertex buffer to draw

       • end - One past the last index of the subset of the vertex buffer to draw

       • type - A member of the ALLEGRO_PRIM_TYPE(3alleg5) enumeration, specifying what  kind  of
         primitive to draw.  Note that ALLEGRO_PRIM_LINE_LOOP and ALLEGRO_PRIM_POINT_LIST are not
         supported.

       Returns: Number of primitives drawn
