SYNOPSIS

Display*display;
Windowwindow;
XIDdeviceid;
Maskmask;

ARGUMENTS

display Specifies the connection to the X server. 

window Specifies the window from which input is desired. 

deviceid Specifies the device from which input is desired. 

mask Specifies the mask of input events that are desired. 

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These requests are part of an HP-proprietary extension to X.  Its functionality has been superseded by the standard X input device extension XSelectExtensionEvent request.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. 

DIAGNOSTICS

BadDevice An invalid device ID was specified.
