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.

BadValue: An invalid first_valuator or num_valuators values was specified.
