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 are 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.
