.SH NAME
XQueryInputVersion, XGetExtensionVersion \- query the version of the input extension.
.SH SYNTAX
.HP
XExtensionVersion *XQueryInputVersion\^(\^Display *\fIdisplay\fP\^, int \fImajor\fP\^, int \fIminor\fP\^);
.HP
XExtensionVersion *XGetExtensionVersion\^(\^Display *\fIdisplay\fP\^, char
*\fIname\fP\^); 
.SH ARGUMENTS
.TP 12
.I display
Specifies the connection to the X server.
.TP 12
.I name
Specifies the extension to be queried.  The input extension name is defined
in the header file \fIXI.h\fP.
.TP 12
.I major
Specifies the major version as supported by the client.
.TP 12
.I minor
Specifies the minor version as supported by the client.
.SH DESCRIPTION
The \fIXQueryInputVersion\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. The client must specify the highest
version numbers it can supports.
.LP
The \fIXGetExtensionVersion\fP request is deprecated and should not be used.
Clients issuing a \fIXgetExtensionVersion\fP request will not be able to use
MPX features.
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.
