Coercing Descriptor Types

The Apple Event Manager provides two functions that allow you to coerce descriptor types. The AECoercePtr function takes a pointer to data and a desired descriptor type and attempts to coerce the data to a descriptor record of the desired descriptor type. The AECoerceDesc function attempts to coerce the data in an existing descriptor record to another descriptor type.
