The input extension name is defined in the header file \fIXI.h\fP. .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. .SH STRUCTURES This request returns an XExtensionVersion structure. .DS typedef struct { int present; short major_version; short minor_version; } XExtensionVersion; .DE .SH DIAGNOSTICS none .SH "SEE ALSO" .br \fI\*(xL\fP
