XSetDVal(1) X Version 11 XSetDVal(1)XSetDeviceValuators(3X11) X FUNCTIONS 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 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.
