SYNTAX
#include <X11/extensions/XInput.h>
XSetDeviceValuators(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 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.
