# XDeviceBell(3x)

ring a bell on a device supported through the input extension

## 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 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.
