NAME

       al_use_shader - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro.h>

              bool al_use_shader(ALLEGRO_SHADER *shader)

DESCRIPTION

       Uses  the shader for subsequent drawing operations on the current target bitmap.  Pass NULL to stop using
       any shader on the current target bitmap.

       Returns true on success.  Otherwise returns false, e.g. because the shader is incompatible with the  tar‐
       get bitmap.
