2 * VARIANT
3 *
4 * Copyright 1998 Jean-Claude Cote
5 *
6 * NOTES
7 * This implements the low-level and hi-level APIs for manipulating VARIANTs.
8 * The low-level APIs are used to do data coercion between different data types.
9 * The hi-level APIs are built on top of these low-level APIs and handle
10 * initialization, copying, destroying and changing the type of VARIANTs.
11 *
12 * TODO:
13 * - The Variant APIs do not support international languages, currency
14 * types, number formating and calendar. They only support U.S. English format.
15 * - The Variant APIs do not the following types: IUknown, IDispatch, DECIMAL and SafeArray.
16 * The prototypes for these are commented out in the oleauto.h file. They need
17 * to be implemented and cases need to be added to the switches of the existing APIs.
18 * - The parsing of date for the VarDateFromStr is not complete.
19 * - The date manipulations do not support date prior to 1900.
20 * - The parsing does not accept has many formats has the Windows implementation.
