Overview

    This is an SGI internal (e.g. not documented or intended to be used
    directly by applications) extension used only to help support
    emulation of IrisGL through OpenGL.

IP Status

    Unknown.

Issues

    Unlikely to be documented; this is ancient work supported only for
    legacy applications.

New Procedures and Functions

    void IglooInterfaceSGIX(enum pname, void *param);

Revision History

    Initial revision (October 5, 2000) - placeholder spec for the actual
    IGLOO interface in use on IRIX gfx. The existing specs were merged
    into a single interface and are both obsolete and AFAIK never
    implemented.
