GXPrCloseDoc

QuickDraw GX sends the GXPrCloseDoc message when an application that supports the Macintosh Printing Manager calls the PrCloseDoc function. You can override the GXPrCloseDoc message to customize the handling of the PrCloseDoc function. Your override of the GXPrCloseDoc message must match the following formal declaration:

OSErr MyPrCloseDoc (TPPrPort aTPPrPort);

aTPPrPort

A pointer to a TPPrPort record.

function result

An error code. The value noErr indicates that the operation was successful.

DESCRIPTION

The default implementation of the GXPrCloseDoc message generates the GXFinishJob message. You can override this message to add any special handling that your printer driver requires at the time that a document is finished printing.

SPECIAL CONSIDERATIONS

You never send the GXPrCloseDoc message yourself.

You almost always forward the GXPrCloseDoc message so that the default implementation can perform its operations.

RESULT CODES

gxSegmentLoadFailedErr	A required code segment could not be found, or there was not enough memory to load it.
gxPrUserAbortErr	The user has canceled printing.

SEE ALSO

The PrCloseDoc function is described in Inside Macintosh: Imaging With QuickDraw.

The GXFinishJob message is described on page 4-54.
