-.TH XkbForceBell __libmansuffix__ __xorgversion__ "XKB FUNCTIONS"
-.SH NAME
-XkbForceBell \- Overrides user preference settings for audible bells to ring the
-bell on the default keyboard

-.SH ARGUMENTS

-.TP
-.I \- percent
-volume for the bell, which can range from -100 to 100 inclusive
-.SH DESCRIPTION
-.LP
-The core X protocol allows only applications to explicitly sound the system bell
-with a
-given duration, pitch, and volume. Xkb extends this capability by allowing clients
-to
-attach symbolic names to bells, disable audible bells, and receive an event whenever
-the
-keyboard bell is rung. For the purposes of this document, the
-.I audible
-bell is defined to be the system bell, or the default keyboard bell, as opposed to
-any
-other audible sound generated elsewhere in the system.
-You can ask to receive XkbBellNotify events when any client rings any one of the
-following:
-
-.IP \(bu 5
-The default bell
-.IP \(bu 5
-Any bell on an input device that can be specified by a bell_class and bell_id pair
-.IP \(bu 5
-Any bell specified only by an arbitrary name. (This is, from the server's point of
-view,
-merely a name, and not connected with any physical sound-generating device. Some
-client
-application must generate the sound, or visual feedback, if any, that is associated
-with
-the name.)
-
-.LP
-You can also ask to receive XkbBellNotify events when the server rings the default
-bell
-or if any client has requested events only (without the bell sounding) for any of
-the
-bell types previously listed.
-
-You can disable audible bells on a global basis. For example, a client that replaces
-the
-keyboard bell with some other audible cue might want to turn off the AudibleBell
-control
-to prevent the server from also generating a sound and avoid cacophony. If you
-disable
-audible bells and request to receive XkbBellNotify events, you can generate feedback
-different from the default bell.
-
-You can, however, override the AudibleBell control by calling one of the functions
-that
-force the ringing of a bell in spite of the setting of the AudibleBell control -
-.I XkbForceDeviceBell
-or
-.I XkbForceBell.
-In this case the server does not generate a bell event.
-
-Just as some keyboards can produce keyclicks to indicate when a key is pressed or
-repeating, Xkb can provide feedback for the controls by using special beep codes.
-The
-AccessXFeedback control is used to configure the specific types of operations that
-generate feedback.
-
-.B Bell Names
-
-You can associate a name to an act of ringing a bell by converting the name to an
-Atom
-and then using this name when you call the functions listed in this chapter. If an
-event
-is generated as a result, the name is then passed to all other clients interested in
-receiving XkbBellNotify events. Note that these are arbitrary names and that there
-is no
-binding to any sounds. Any sounds or other effects (such as visual bells on the
-screen)
-must be generated by a client application upon receipt of the bell event containing
-the
-name. There is no default name for the default keyboard bell. The server does
-generate
-some predefined bells for the AccessX controls. These named bells are shown in the
-Table 1; the name is included in any bell event sent to clients that have requested to
-receive XkbBellNotify events.

-.B Audible Bells
-
-Using Xkb you can generate bell events that do not necessarily ring the system bell.
-This
-is useful if you need to use an audio server instead of the system beep. For
-example,
-when an audio client starts, it could disable the audible bell (the system bell) and
-then
-listen for XkbBellNotify events. When it receives a XkbBellNotify event, the audio
-client
-could then send a request to an audio server to play a sound.
-
-You can control the audible bells feature by passing the XkbAudibleBellMask to
-.I XkbChangeEnabledControls.
-If you set XkbAudibleBellMask on, the server rings the system bell when a bell event
-occurs. This is the default. If you set XkbAudibleBellMask off and a bell event
-occurs,
-the server does not ring the system bell unless you call
-.I XkbForceDeviceBell
-or
-.I XkbForceBell.
-
-Audible bells are also part of the per-client auto-reset controls.
-
-Bell Functions
-
-Use the functions described in this section to ring bells and to generate bell
-events.
-
-The input extension has two types of feedbacks that can generate bells - bell
-feedback
-and keyboard feedback. Some of the functions in this section have
-.I bell_class
-and
-.I bell_id
-parameters; set them as follows: Set
-.I bell_class
-to BellFeedbackClass or KbdFeedbackClass. A device can have more than one feedback
-of
-each type; set
-.I bell_id
-to the particular bell feedback of
-.I bell_class
-type.
-
-Table 2 shows the conditions that cause a bell to sound or an XkbBellNotifyEvent to be generated when a bell function is
-called.

-.SH STRUCTURES
-.LP
-Xkb generates XkbBellNotify events for all bells except for those resulting from
-calls to
-.I XkbForceDeviceBell
-and
-.I XkbForceBell.
-To receive XkbBellNotify events under all possible conditions, pass
-XkbBellNotifyMask in
-both the
-.I bits_to_change
-and
-.I values_for_bits
-parameters to
-.I XkbSelectEvents.
-
-The XkbBellNotify event has no event details. It is either selected or it is not.
-However, you can call
-.I XkbSelectEventDetails
-using XkbBellNotify as the
-.I event_type
-and specifying XkbAllBellNotifyMask in
-.I bits_to_change
-and
-.I values_for_bits.
-This has the same effect as a call to
-.I XkbSelectEvents.
-
-The structure for the XkbBellNotify event type contains:
-.nf
-
- typedef struct _XkbBellNotify {
- int type; /\(** Xkb extension base event code */
- unsigned long serial; /\(** X server serial number for event */
- Bool send_event; /\(** True => synthetically generated */
- Display * display; /\(** server connection where event generated */
- Time time; /\(** server time when event generated */
- int xkb_type; /\(** XkbBellNotify */
- unsigned int device; /\(** Xkb device ID, will not be XkbUseCoreKbd */
- int percent; /\(** requested volume as % of max */
- int pitch; /\(** requested pitch in Hz */
- int duration; /\(** requested duration in microseconds */
- unsigned int bell_class; /\(** X input extension feedback class */
- unsigned int bell_id; /\(** X input extension feedback ID */
- Atom name; /\(** "name" of requested bell */
- Window window; /\(** window associated with event */
- Bool event_only; /\(** False -> the server did not produce a beep */
- } XkbBellNotifyEvent;
-
-.fi
-If your application needs to generate visual bell feedback on the screen when it
-receives
-a bell event, use the window ID in the XkbBellNotifyEvent, if present.
