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

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.
