Error on Page 4-163 of QDGX Printing Extensions and Drivers

Important for all Apple Printing and Graphics Developers:

The information in this Technical Q & A is still relevant up to and including Mac OS 7.6 with QuickDraw GX 1.1.5. Beginning with the release of Mac OS 8.0, however, Apple plans to deliver a system which incorporates QuickDraw GX graphics and typography only. QuickDraw GX printer drivers and GX printing extensions will not be supported in Mac OS 8.0 or in future Mac OS releases. Apple's goal is to simplify the user experience of printing by unifying the Macintosh graphic and printing architectures and standardizing on the classic Printing Manager.

For details on Apple's official announcement, refer to </dev/technotes/gxchange.html>

Q: There is an error on page 4-163 of QDGX Printing Extensions and Drivers. The line that reads:

OSErr MyWriteStatusToDTPWindow (gxStatusRecord aStatusRecord,
    gxDisplayRecord aDisplayRecord);

should be corrected to read: 

OSErr MyWriteStatusToDTPWindow (gxStatusRecord *aStatusRecord,
    gxDisplayRecord *aDisplayRecord);

A: You're right. It's a typographical error that also appears in the new Toolbox Assistant electronic version of the documentation. The interface files are correct, however. As rule, it's best to check the interfaces if you need the declaration of a function or callback.
