XGetExtensionVersion(3)    X FUNCTIONS    XGetExtensionVersion(3)



NAME
       XGetExtensionVersion  -  query  the  version  of the input
       extension.

SYNTAX
       XExtensionVersion *XGetExtensionVersion(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.
