Object Callback Functions

If an Apple event parameter consists of an object specifier record, your handler for the Apple event typically calls AEResolve to begin the process of locating the requested Apple event objects. The AEResolve function in turn calls object accessor functions and, if necessary, object callback functions provided by your application when it needs the information they can provide.

This section provides declarations for the seven object callback functions that your application can provide: the object-counting function (MyCountObjects), object-comparison function (MyCompareObjects), token disposal function (MyDisposeToken), error callback function (MyGetErrorDesc), mark token function (MyGetMarkToken), object-marking function (MyMark), and mark-adjusting function (MyAdjustMarks).

For information about writing and installing object callback functions, see "Writing Object Callback Functions," which begins on page 6-54.
