See include/osg/GLExtensions. Please note you'll need to have a valid graphics context, and for the extensions to be initialised before the functions will work as you can only do OpenGL calls from a thread with a valid graphics context. If you have happy do debug work on your app, then enable the verbose debug messages and this will output the lists of supported extensions for you. set the env var OSG_NOTIFY_LEVEL to DEBUG. Robert.
