       XSetDeviceValuators - initialize the valuators on an extension input device

       XSetDeviceValuators(display, device, valuators, first_valuator, num_valuators)
	     Display *display;
	     XDevice *device;
	     int *valuators;
	     int first_valuator;
	     int num_valuators;

       display	   Specifies the connection to the X server.

       device	   Specifies the device whose valuators are to be initialized.

       valuators   Specifies a pointer to an array of integer values to be used to initialize the
		   device valuators.

		   Specifies the first valuator to be set.  Valuators are numbered beginning with

		   Specifies the number of valuators to be set.

       The  XSetDeviceValuators  request  sets	the  current  values of the valuators of an input
       device.	The valuators in the range first_valuator to (first_valuator + num_valuators) are
       set  to	the  specified	values.   Valuators are numbered beginning with 0.  Not all input
       devices support initialization of valuator values.  If this request is made  to	a  device
       that does not support valuators initialization, a BadMatch error will occur.

       If  the	request  succeeds,  a  status  of Success is returned.	If another client has the
       device grabbed, a status of AlreadyGrabbed is returned.

       XSetDeviceValuators can generate a BadLength, BadDevice , BadMatch, or BadValue error.

       BadDevice   An invalid device was specified.  The specified device does not exist  or  has
		   not been opened by this client via XOpenInputDevice.

       BadMatch    This  error	may  occur if an XSetDeviceValuators request is made specifying a
		   device that has no valuators and reports no axes  of  motion,  or  if  such	a
		   request is made specifying a device that does not support valuator initializa-

       BadValue    An invalid first_valuator or num_valuators values was specified.
