/* This module provides some helper APIs for creating a VCalendar object. Note on APIs: 1. The APIs does not attempt to verify if the arguments passed are correct. 2. Where the argument to an API is not applicable, pass the value 0. 3. See the test program at the bottom of this file as an example of usage. 4. This code calls APIs in vobject.c. */ /*************************************************************************** (C) Copyright 1996 Apple Computer, Inc., AT&T Corp., International Business Machines Corporation and Siemens Rolm Communications Inc.
