DESCRIPTION

       extension implemented by the server associated with connection dpy.  Im‐
       plementations  with the same major version number are upward compatible,
       meaning that the implementation with the higher minor number is a super‐
       set of the version with the lower minor number.

       maj and min do not return values if they are specified as NULL.

ERRORS
       glXQueryVersion returns False if it fails, True otherwise.
