NAME

XHPSetInputDevice - Open a device for X input. 

SYNOPSIS

#include <X11/XHPlib.h>
 XHPSetInputDevice (display, deviceid, mode)
Display∗display;
XIDdeviceid;
intmode;

ARGUMENTS

display Specifies the connection to the X server. 

deviceid Specifies the ID of the desired device. 

mode Specifies the desired mode of access. 

DESCRIPTION

This function is provided to support input devices other than the X keyboard device and the X pointer device. 

Client programs use the XHPSetInputDevice to open an input device for extended input and to close the device.  XHPSetInputDevice requires a mode parameter that specifies the function being requested (ON or OFF) and, if the function is ON,  whether the device should be opened as an extension to the X keyboard or pointer (SYSTEM_EVENTS), or as an independently selectable device (DEVICE_EVENTS).  The value of the mode parameter is set by ORing together the above constants, which may be obtained by including the file <X11/XHPlib.h>. 

To open an input device as a device whose input can be selected independent of the X keyboard and X pointer, the client program would use the mode ON OR’d with the mode DEVICE_EVENTS.  To open an input device as an extension of the X keyboard or X pointer, the client program would use the mode ON or’d with the mode SYSTEM_EVENTS.  Valid values for the mode parameter are:

 ON | SYSTEM_EVENTS
ON | DEVICE_EVENTS
OFF

This request will fail with a BadMode error if some other client is already using the device with a different mode. 

DIAGNOSTICS

BadMode An invalid mode was specified. 

BadDevice An invalid device ID was specified. 

RETURN VALUE

none
