.SH "DESCRIPTION"
.sp
.if n \{\
.RS 4
.\}
.nf
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\&.
.fi
.if n \{\
.RE
.\}
.sp
.if n \{\
.RS 4
.\}
.nf
The volume at which the bell is rung when the percent argument
is nonnegative is: base \- [(base * percent) / 100] + percent
.fi
.if n \{\
.RE
.\}
.sp
.if n \{\
.RS 4
.\}
.nf
The volume at which the bell rings when the percent argument is
negative is: base + [(base * percent) / 100]
.fi
.if n \{\
.RE
.\}
.sp
.if n \{\
.RS 4
.\}
.nf
To change the base volume of the bell, use
XChangeFeedbackControl\&.

.sp
.if n \{\

.nf
XDeviceBell can generate a BadDevice or a BadValue error\&.

BadDevice
       An invalid device was specified\&. The specified device
       does not exist, or has not been opened by this client
       via XOpenInputDevice\&.
