 "NAME"
XSetDeviceValuators - initialize the valuators on an extension input device

 "SYNOPSIS"
#include <X11/extensions/XInput.h>



XSetDeviceValuators( 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.



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.
