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 thedevice valuators.
first_valuator
Specifies the first valuator to be set. Valuators are
numbered beginning withzero.
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.
