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  pro-
       tocol  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  proto-
       col requests contained by previous versions.

       You should use XFree to free the XExtensionVersion structure.

	       short  major_version;
	       short  minor_version; } XExtensionVersion;
