NAME

       glutLayerGet - retrieves GLUT state pertaining to the layers of the current window.

SYNTAX

       int glutLayerGet(GLenum info);

ARGUMENTS

       info	 Name of device information to retrieve.

       GLUT_OVERLAY_POSSIBLE
	       Whether an overlay could be established for the current window given the current initial display mode. If false, glutEstablishOver-
	       lay will fail with a fatal error if called.

       GLUT_LAYER_IN_USE
	       Either GLUT_NORMAL or GLUT_OVERLAY depending on whether the normal plane or overlay is the layer in use.

       GLUT_HAS_OVERLAY
	       If the current window has an overlay established.

       GLUT_TRANSPARENT_INDEX
	       The transparent color index of the overlay of the current window; negative one is returned if no overlay is in use.

       GLUT_NORMAL_DAMAGED
	       True if the normal plane of the current window has damaged (by window system activity) since the last display  callback	was  trig-
	       gered. Calling glutPostRedisplay will not set this true.

       GLUT_OVERLAY_DAMAGED
	       True  if  the overlay plane of the current window has damaged (by window system activity) since the last display callback was trig-
	       gered. Calling glutPostRedisplay or glutPostOverlayRedisplay will not set this true. Negative one is returned if no overlay  is	in
	       use.

DESCRIPTION

       glutLayerGet  retrieves	GLUT  layer information for the current window represented by integers. The info parameter determines what type of
       layer information to return.
