DESCRIPTION
The XQueryInputVersion 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. The client must specify the highest
version numbers it can supports.
The XGetExtensionVersion request is deprecated and should not be used.
Clients issuing a XgetExtensionVersion request will not be able to use
MPX 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.
STRUCTURES
