This extension is a minimal set of client and server extensions required to completely test the X11 server with no user intervention. This extension is not intended to support general journaling and playback of user actions.
These routines manipulate otherwise hidden client\-side behavior. The actual implementation will depend on the details of the actual language binding and what degree of request buffering, GContext caching, and so on, is provided. In the C binding, routines are provided to access the internals of two opaque data structures \(em
Visuals \(em and to discard any requests pending within the output buffer of a connection. The exact details can be expected to differ for other language bindings.

\fIServer Requests\fR
The first of these requests is similar to that provided in most extensions: it allows a client to specify a major and minor version number to the server and for the server to respond with major and minor versions of its own. The remaining two requests allow the following:
Perhaps most importantly, limited synthesis of input device events, almost as if a cooperative user had moved the pointing device or pressed a key or button.
False. If the extension is supported, *event_base would be set to the event number for the first event for this extension and *error_base would be set to the error number for the first error for this extension. As no errors or events are defined for this version of the extension, the values returned here are not defined (nor useful). If the extension is supported, *major_version and *minor_version are set to the major and minor version numbers of the extension supported by the display. Otherwise, none of the arguments are set.
\fICurrentTime\fR, then this is interpreted as no delay at all). No other requests from this client will be processed until this delay, if any, has expired and subsequent processing of the simulated event has been completed.

requests the server to simulate a movement of the pointer to the specified position (x, y) on the root window of screen_number; otherwise, the request is ignored. If screen_number is \-1, the current screen (that the pointer is on) is used.

requests the server to simulate a movement of the pointer by the specified offsets (x, y) relative to the current pointer position on screen_number; otherwise, the request is ignored. If screen_number is \-1, the current screen (that the pointer is on) is used.
\fICurrentTime\fR, then this is interpreted as no delay at all). No other requests from this client will be processed until this delay, if any, has expired and subsequent processing of the simulated event has been completed.
All routines that have return type Status will return nonzero for success and zero for failure. Even if the XTEST extension is supported, the server may withdraw such facilities arbitrarily; in which case they will subsequently return zero.
