Description

A message that is sent at a specific point in a process. Callbacks are usually used to notify an object about the progress of a process that the object started.

For example, a player might send a callback message when the movie reaches a certain frame. Or the Internet library might send a callback to the object whose script started a file transfer when the transfer is completed.
