 "SYNOPSIS"
#include <X11/extensions/XInput.h>



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



display

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



 "DESCRIPTION"

.\}

The XGetExtensionVersion request is deprecated and should not
be used in XI2 applications. Clients issuing a XGetExtensionVersion
request will not be able to use XI2 features.




.\}


.\}

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.
