GLXQUERYEXTENSION(3G)						   OpenGL Manual					     GLXQUERYEXTENSION(3G)

NAME

       glXQueryExtension - indicate whether the GLX extension is supported

C SPECIFICATION

       Bool glXQueryExtension(Display * dpy, int * errorBase, int * eventBase);

PARAMETERS

       dpy
	   Specifies the connection to the X server.

       errorBase
	   Returns the base error code of the GLX server extension.

       eventBase
	   Returns the base event code of the GLX server extension.

DESCRIPTION

       glXQueryExtension returns True if the X server of connection dpy supports the GLX extension, False otherwise. If True is returned, then
       errorBase and eventBase return the error base and event base of the GLX extension. These values should be added to the constant error and
       event values to determine the actual event or error values. Otherwise, errorBase and eventBase are unchanged.

       errorBase and eventBase do not return values if they are specified as NULL.

C SPECIFICATION

       void glXGetSelectedEvent(Display * dpy, GLXDrawable draw, unsigned long * event_mask);

PARAMETERS

       dpy
	   Specifies the connection to the X server.

       draw
	   Specifies a GLX drawable. Must be a GLX pixel buffer or a window.

       event_mask
	   Returns the events that are selected for draw.

DESCRIPTION

       glXGetSelectedEvent returns in event_mask the events selected for draw.

       glXGetSelectedEvent is available only if the GLX version is 1.3 or greater.

       If the GLX version is 1.1 or 1.0, the GL version must be 1.0. If the GLX version is 1.2, then the GL version must be 1.1. If the GLX
       version is 1.3, then the GL version must be 1.2.
