Routines for Responding to Apple Events

Getting the Sizes and Descriptor Types of Descriptor Records
The Apple Event Manager provides four routines that allow you to get the sizes and descriptor types of descriptor records that are not part of an Apple event record. The AESizeOfNthItem function returns the size and descriptor type of a descriptor record in a descriptor list.The AESizeOfKeyDesc function returns the size and descriptor type of a keyword-specified descriptor record in an AE record. You can get the size and descriptor type of an Apple event parameter or Apple event attribute using the AESizeOfParam and AESizeOfAttribute functions.
