A callback is a function that will be called as a result of some
pre-determined event or condition.  The application code starts a
function or routine that never returns.  To get back to the
application code, the callback function is called.

For example, in networking, a callback function will be defined to be
called by the network code in response to receiving a packet.

Or, in X11, a callback functions are used to handle events like mouse
buttons, etc.
