NAME

       al_build_shader - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro.h>

              bool al_build_shader(ALLEGRO_SHADER *shader)

DESCRIPTION

       This  is required before the shader can be used with al_use_shader(3alleg5).  It should be
       called   after   successfully   attaching   the   pixel   and/or   vertex   shaders   with
       al_attach_shader_source(3alleg5) or al_attach_shader_source_file(3alleg5).

       Returns  true  on success and false on error, in which case the error log is updated.  The
       error log can be retrieved with al_get_shader_log(3alleg5).

              Note: If you are  using  the  ALLEGRO_PROGRAMMABLE_PIPELINE  flag,  then  you  must
              specify both a pixel and a vertex shader sources for anything to be rendered.
