DESCRIPTIONThe 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:
The volume at which the bell rings when the percent argument is negative is:
To change the base volume of the bell, use XChangeFeedbackControl. XDeviceBell can generate a BadDevice or a BadValue error. DIAGNOSTICS
