GXCleanupStartSendPage

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

void GXCleanupStartSendPage (void);

DESCRIPTION

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

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