NAME

       al_get_opengl_fbo - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro_opengl.h>

              GLuint al_get_opengl_fbo(ALLEGRO_BITMAP *bitmap)

DESCRIPTION

       Returns  the  OpenGL  FBO id internally used by the given bitmap if it uses one, otherwise
       returns zero.  No attempt will be made to create an FBO if the bitmap is not owned by  the
       current display.

       The  FBO  returned by this function will only be freed when the bitmap is destroyed, or if
       you call al_remove_opengl_fbo(3alleg5) on the bitmap.

              Note: In Allegro 5.0.0 this function only returned an FBO which had previously been
              created  by  calling al_set_target_bitmap(3alleg5).  It would not attempt to create
              an FBO itself.  This has since been changed.
