XSetDeviceMode(display, device, mode)
Display *display;
XDevice *device;
int _mode;
display Specifies the connection to the X server.
device Specifies the device whose mode is to be
changed.
mode Specifies the mode. You can pass Absolute , or
Relative.
The XSetDeviceMode request changes the mode of an input dev-
ice that is capable of reporting either absolute positional
information or relative motion information. Not all input
devices are capable of reporting motion data, and not all
are capable of changing modes from Absolute to Relative.
XSetDeviceMode can generate a BadDevice or BadMode error.
BadDevice An invalid device was specified. The specified
device does not exist or has not been opened by
this client via XOpenInputDevice. This error
may also occur if some other client has caused
the specified device to become the X keyboard or
X pointer device via the XChangeKeyboardDevice
or XChangePointerDevice requests.
BadMatch This error may occur if an XSetDeviceMode
request is made specifying a device that has no
valuators and reports no axes of motion.
BadMode An invalid mode was specified. This error will
also be returned if the specified device is not
capable of supporting the XSetDeviceMode
request.
