DESCRIPTION

       The XGetExtensionVersion request  queries  the  version  of  the  input
       extension,  and returns an XExtensionVersion structure.  This structure
       contains a major_version and minor_version number which can be compared
       with  constants  defined  in  XI.h.   Support  for  additional protocol
       requests added to the input extension  after  its  initial  release  is
       indicated  by  a  version  number  corresponding to the added requests.
       Each version contains all the protocol requests contained  by  previous
       versions.

       You should use XFree to free the XExtensionVersion structure.
