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.
