GLUTUSELAYER(3)

NAME
glutUseLayer - Allows you to switch between normal and layer mode.

LIBRARY
OpenGLUT - overlays

SYNOPSIS
#include <openglut.h>
void
glutUseLayer(GLenum layer);

PARAMETERS

layer Whether to be in a layer or in the normal window.

DESCRIPTION
By default, OpenGLUT operates in "normal" mode, with respect to layers. If you have a layer open and wish to operate on the layer, you must use glutUseLayer().

layer can take on the following values, indicating the layer mode to use:

- GLUT_NORMAL

- GLUT_LAYER

CAVEATS
Unimplemented.

It is unclear what the consequences are if you are in GLUT_OVERLAY mode and switch to another (or the same) window via glutSetWindow(). What if the target has a layer? What if it doesn't?
