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 thedevice valuators.
 

 first_valuator
        Specifies the first valuator to be set. Valuators are
        numbered beginning withzero.
 

 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.
