glXQueryVersion  -  return  the version numbers of the GLX
       extension



C SPECIFICATION

       Bool glXQueryVersion( Display *dpy,
                             int *major,
                             int *minor )



PARAMETERS

       dpy    Specifies the connection to the X server.

       major  Returns the major version number of the GLX  server
              extension.

       minor  Returns  the minor version number of the GLX server
              extension.


DESCRIPTION

       glXQueryVersion returns the major and minor  version  num-
       bers  of the GLX extension implemented by the server asso-
       ciated with connection dpy.  Implementations with the same
       major  version  number are upward compatible, 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.
