|
|
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

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.
