XSetDeviceValuators(3X11)
X11R6
NAME
  XSetDeviceValuators - initialize the valuators on an extension input device

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

ARGUMENTS
  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.

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

  num_valuators
      Specifies the number of valuators to be set.

DESCRIPTION
  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.

DIAGNOSTICS
  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 initialization.

  BadValue
	  An invalid first_valuator or num_valuators values was specified.
