Clock Component Functions / Using the Callback Functions

ClockDisposeCallBack

Your clock component's ClockDisposeCallBack function disposes of the memory associated with the specified callback event.

pascal ComponentResult ClockDisposeCallBack 
                                    (ComponentInstance aClock,
                                     QTCallBack cb);

aClock

Specifies the clock for the operation. Applications obtain this identifier from the Component Manager's OpenComponent function.

cb

Specifies the callback event for the operation. The Movie Toolbox obtains this value from your component's ClockNewCallBack function (described on page 11-9).

DESCRIPTION

The Movie Toolbox calls this function when an application discards its callback event
by calling the DisposeCallBack function. Your clock component should cancel the callback event before you dispose of it.

You should not call this function at interrupt time.
