XSetDeviceValuators(3) X FUNCTIONS XSetDeviceValuators(3)
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 num-
bered beginning with zero.
num_valuators
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
BadDevice An invalid device was specified. The specified device does
not exist or has not been opened by this client via XOpen-
InputDevice.
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 spec-
ified.
