DESCRIPTION

       glXQueryVersion  returns the major and minor version numbers of the GLX
       extension implemented by the server  associated  with  connection  dpy.
       Implementations  with the same major version number are upward compati-
       ble, meaning that the implementation with the higher minor number is  a
       superset of the version with the lower minor number.

       major and minor do not return values if they are specified as NULL.

ERRORS

       glXQueryVersion returns False if it fails, True otherwise.

       major and minor are not updated when False is returned.
