.SH DESCRIPTION
|
||
|
|
The \fIXGetExtensionVersion\fP request queries the version of the input
|
||
|
|
extension, and returns an \fIXExtensionVersion\fP structure. This structure
|
||
|
|
contains a major_version and minor_version number which can be compared
|
||
|
|
with constants defined in \fIXI.h\fP. 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.
|
||
|
|
.LP
|
||
|
|
You should use \fIXFree\fP to free the \fIXExtensionVersion\fP structure.
|
