NAME

6       al_draw_vertex_buffer - Allegro 5 API

SYNOPSIS

9              #include <allegro5/allegro_primitives.h>
10
11              int al_draw_vertex_buffer(ALLEGRO_VERTEX_BUFFER* vertex_buffer,
12                 ALLEGRO_BITMAP* texture, int start, int end, int type)
13

DESCRIPTION

15       Draws a subset of the passed vertex buffer.  The vertex buffer must not
16       be locked.  Additionally, to draw onto memory bitmaps  or  with  memory
17       bitmap  textures  the vertex buffer must support reading (i.e.  it must
18       be created with the ALLEGRO_PRIM_BUFFER_READWRITE).
19
20       Parameters:
21
22       · vertex_buffer - Vertex buffer to draw
23
24       · texture - Texture to use, pass NULL to use only  color  shaded  prim‐
25         itves
26
27       · start - Start index of the subset of the vertex buffer to draw
28
29       · end  -  One past the last index of the subset of the vertex buffer to
30         draw
31
32       · type - A member of the ALLEGRO_PRIM_TYPE(3)  enumeration,  specifying
33         what kind of primitive to draw
34
35       Returns: Number of primitives drawn
