# NAME

XSetDeviceValuators - initialize the valuators on an extension input device

# SYNOPSIS

    #include <X11/extensions/XInput.h>

    XSetDeviceValuators( Display *display,

                         XDevice *device,

                         int *valuators,

                         int first_valuator,

                         int num_valuators);

    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.
