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.
BadValue
An invalid first_valuator or num_valuators values was specified.
