XDeviceBell(3X11)		  X FUNCTIONS		     XDeviceBell(3X11)

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

SYNTAX
       Status XDeviceBell(Display *display, XDevice  *device,  XID  *feedback‐
	      class, 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	speci‐
       fied 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	 XGetFeedback‐
       Control 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  non‐
       negative is:

	      base - [(base * percent) / 100] + percent

       The  volume  at which the bell rings when the percent argument is nega‐
       tive 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 XOpen‐
		   InputDevice.

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