NAME
       al_get_default_shader_source - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro.h>

              char const *al_get_default_shader_source(ALLEGRO_SHADER_PLATFORM platform,
                 ALLEGRO_SHADER_TYPE type)


DESCRIPTION
       Returns a string containing the source code to Allegro's default vertex
       or pixel shader appropriate for the passed platform.  The
       ALLEGRO_SHADER_AUTO value means GLSL is used if OpenGL is being used
       otherwise HLSL.  ALLEGRO_SHADER_AUTO requires that there is a current
       display set on the calling thread.  This function can return NULL if
       Allegro was built without support for shaders of the selected platform.

SINCE
       5.1.6
