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_re‐
       move_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.
