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\&.
