bell - Ring a display's bell
bell ?-displayof window? ?-nice?
This command rings the bell on the display for window and returns an empty string. If the -displayof option is omitted, the display of the
application's main window is used by default. The command uses the current bell-related settings for the display, which may be modified
with programs such as xset.
If -nice is not specified, this command also resets the screen saver for the screen. Some screen savers will ignore this, but others will
reset so that the screen becomes visible again.

XDeviceBell - ring a bell on a device supported through the input extension
Status XDeviceBell(display, device, feedbackclass, feedbackid, percent)
Specifies the connection to the X server. Specifies the device with which the bell is associated. Specifies the class of the feedback
with which the bell is associated. Specifies the id of the feedback with which the bell is associated. Specifies the volume in the range
-100 to 100 at which the bell should be rung.
The XDeviceBell request causes the server to ring a bell on the specified feedback of the specified device, if possible. The specified vol-
ume 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 feedback-
class 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.
An invalid device was specified. The specified device does not exist, or has not been opened by this client via XOpenInputDevice. An
invalid feedbackclass, feedbackid, or percent value was specified.
