NAME
       XGetExtensionVersion  -  query  the  version  of the input
       extension.

SYNTAX
       XExtensionVersion *XGetExtensionVersion(display, name)
             Display *display;
             char *name;

ARGUMENTS
       display     Specifies the connection to the X server.

       name        Specifies the extension to  be  queried.   The
                   input  extension name is defined in the header
                   file XI.h.

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  struc-
       ture.
