XSetDeviceValuators(XXVersion 11 (ReleasXSetDeviceValuators(3X11)
NAME
XSetDeviceValuators - initialize the valuators on an
extension input device
SYNTAX
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.
