24DESCRIPTION
25-----------
26
27   The XGetExtensionVersion request is deprecated and should not
28   be used in XI2 applications. Clients issuing a XGetExtensionVersion
29   request will not be able to use XI2 features.
30
31   The XGetExtensionVersion request queries the version of the input
32   extension, and returns an XExtensionVersion structure. This structure
33   contains a major_version and minor_version number which can be compared
34   with constants defined in XI.h. Support for additional protocol
35   requests added to the input extension after its initial release
36   is indicated by a version number corresponding to the added
37   requests. Each version contains all the protocol requests
38   contained by previous versions.
39
40   You should use XFree to free the XExtensionVersion structure.
