Application-Defined Error, Warning, and Notice Handlers

You can use error, warning, and notice handlers to manage problems that occur when your application is running. When QuickDraw GX detects an error, warning, or notice it will call your handler. Your function can then respond accordingly. You can also use error and warning handlers with the non-debugging version of QuickDraw GX to provide part of your user interface.

Application-defined error, warning, and notice handlers are described in the section "Installing an Error, Warning, or Notice Handler" beginning on page 3-40.
