XSetDeviceValuators(3X11) X FUNCTIONS XSetDeviceValuators(3X11)NAMEXSetDeviceValuators - 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. Valu-
ators 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 initial-
ization 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 speci-
fied 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

XSetDeviceValuators(3X11) X FUNCTIONS XSetDeviceValuators(3X11)
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.
