NAME

       bell - Ring a display's bell

SYNOPSIS

       bell ?-displayof window? ?-nice?
_________________________________________________________________

DESCRIPTION

       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.

NAME

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

SYNTAX

       Status XDeviceBell(Display *display, XDevice *device, XID *feedbackclass, XID *feedbackid, int *percent);

ARGUMENTS

       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  feedback-
       class  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 XOpenInputDe-
		   vice.

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