XBell() 																   XBell()

Name
  XBell - ring the bell.

Synopsis
  XBell(display, percent)
	Display *display;
	int percent;

Arguments
  display  Specifies a connection to an X server; returned from XOpenDisplay().

  percent  Specifies the volume for the bell, relative to the base volume set with XChangeKeyboardControl().  Possible values are -100 (off),
	   through 0 (base volume), to 100 (loudest) inclusive.

Description
  Rings the bell on the keyboard at a volume relative to the base volume, if possible.	percent can range from -100 to 100 inclusive (else  a
  BadValue error).  The volume at which the bell is rung when percent is nonnegative is:
       volume = base - [(base * percent) / 100] + percent
  and when percent is negative:
       volume = base + [(base * percent) / 100]

  To change the base volume of the bell, set the bell_percent variable of XChangeKeyboardControl().

Errors
  BadValue  percent < -100 or percent >100.

NAME

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

SYNTAX

       Status XDeviceBell(display, device, feedbackclass, feedbackid, percent)
	     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.
