NAME
XDeviceBell - ring a bell on a device supported through the input extension

SYNOPSIS

#include <X11/extensions/XInput.h>

Status XDeviceBell( Display *display,
                    XDevice *device,
                    XID feedbackclass,
                    XID feedbackid,
                    int percent);
display
       Specifies the connection to the X server.

device
       Specifies the device with which the bell is associated.

feedbackclass
       Specifies the class of the feedback with which the bell
       is associated.

feedbackid
       Specifies the id of the feedback with which the bell is
       associated.

percent
       Specifies the volume in the range -100 to 100 at which
       the bell should be rung.

DESCRIPTION

    The XDeviceBell request causes the server to ring a bell on the
    specified feedback of the specified device, if possible. The
    specified volume is relative to the base volume for the bell.
    If an invalid device is specified, a BadDevice error will be
    returned. The feedbackclass and feedbackid parameters contain
    values returned by an XGetFeedbackControl request and uniquely
    identify the bell to ring. If a feedbackclass is specified that
    does not support a bell, or if a nonexistent feedbackid is
    specified, or a percent value is specified that is not in the
    range -100 to 100, a BadValue error will be returned.

    The volume at which the bell is rung when the percent argument
    is nonnegative is: base - [(base * percent) / 100] + percent

    The volume at which the bell rings when the percent argument is
    negative is: base + [(base * percent) / 100]

    To change the base volume of the bell, use
    XChangeFeedbackControl.

    XDeviceBell can generate a BadDevice or a 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.

    BadValue
           An invalid feedbackclass, feedbackid, or percent value
           was specified.
