RTX Handler

RTX provides a handler to process exceptions that occur in an RTSS process. (If an exception occurs in a native Windows application, the Windows operating system handles it.) When the RTX handler encounters an error, it initiates one of the following actions:

Freezes and/or terminates the process
Modifies the application environment and continues
Executes an orderly shutdown, known as a Green Screen

If an exception occurs within an ISR (such as an RTX hardware interrupt or RTX timer interrupt), RTX immediately initiates an RTX Green Screen stop message.

In versions of RTX prior to RTX 7.0, if a fault occurred during exception processing, the RTX handler immediately initiated a double fault and a Green Screen. Now, you can configure RTX exception handling so that when a fault occurs, RTX stops the process and either creates an RTX-enabled minidump or inserts a debug break.
