Functions / Handling Error Conditions in a Message Override

GXCleanupStartJob

You can use the GXCleanupStartJob function to notify QuickDraw GX that it needs to clean up any actions that it took after receiving a GXStartJob message from your printing extension or printer driver.

void GXCleanupStartJob (void);

DESCRIPTION

You need to call the GXCleanupStartJob function if you encounter an error in your override of the GXStartJob message and you have already forwarded the message.

When you call GXCleanupStartJob, QuickDraw GX sends the GXCleanupStartJob message, which allows all of the message handlers to reverse any actions that they took in their overrides of the GXStartJob message, such as allocating storage or modifying state information.

The GXStartJob and GXCleanupStartJob messages are described in the chapter "Printing Messages."
