Allows you to encapsulate calls to
AEBuild in your own
stdarg-style wrapper routines, using techniques similar to those allowed by vsprintf.

This function and related “AEBuild” routines provide a very simple translation service for converting specially formatted strings into complex Apple event descriptors. Normally, creating complex Apple event descriptors requires a large number of calls to Apple event Manager routines to build up the descriptor piece by piece. The
v function and related routines allow you to consolidate all of the calls required to construct a complex Apple event descriptor into a single system call that creates the desired structure as directed by a format string that you provide.
