DESCRIPTION
These requests are part of an HP-proprietary extension to X. Its
functionality has been superseded by the standard X input device
extension XSelectExtensionEvent request. You should use
XSelectExtensionEvent instead of XHPSelectExtensionEvent if possible.
This request is provided to support the use of input devices other than
the X keyboard and X pointer device. It allows input from other input
devices to be selected independently from that coming from the X
pointer and keyboard.
XHPSelectExtensionEvent requests the server to send an extended event
that matches the specified event mask and comes from the specified
device and window. In order to use this request, the client program
must first determine the appropriate deviceid by using the
XHPListInputDevice request, and the appropriate event mask by using the
XHPGetExtEventMask request. Multiple event masks returned by
XHPGetExtEventMask may be OR'd together and specified in a single
request to XHPSelectExtensionEvent.
This request cannot be used to select any of the core X events, or to
receive input from the X Keyboard or X pointer device. The core
XSelectInput request should be used for that purpose.
