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 connec-
tion 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.
