Overview
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.
