XSetDeviceValuators(3X11)XSetDeviceValuators(3X11)NAMEXSetDeviceValuators - 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
Specifies the connection to the X server. Specifies the device whose
valuators are to be initialized. Specifies a pointer to an array of
integer values to be used to initialize the device valuators. Speci‐
fies the first valuator to be set. Valuators are numbered beginning
with zero. Specifies the number of valuators to be set.
DESCRIPTION
The XSetDeviceValuators request sets the current values of the valua‐
tors of an input device. The valuators in the range first_valuator to
(first_valuator + num_valuators) are set to the specified values. Val‐
uators 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
An invalid device was specified. The specified device does not exist
or has not been opened by this client via XOpenInputDevice. 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 ini‐
tialization. An invalid first_valuator or num_valuators values was
specified.
