XSetDeviceValuators(3X11) X Version 11(Release 5) XSetDeviceValuators(3X11)
NAME
XSetDeviceValuators - 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. 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.
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.
