SYNOPSIS

9              #include <allegro5/allegro.h>

DESCRIPTION

14       Uses the shader for subsequent drawing operations on the current target
15       bitmap.  Pass NULL to stop using any shader on the current target  bit‐
16       map.

18       Returns  true  on  success.  Otherwise returns false, e.g.  because the
19       shader is incompatible with the target bitmap.
