#include <string.h>
#include <stdlib.h>
Reimplement/document every low level variant function. Implement DECIMAL, I8, UI8 types and other missing conversions. VariantChangeType: Use LOCALE_USER_DEFAULT as per MSDN. VariantChangeTypeEx: Support new types, pass proper flags. VarNumFromParseNum: Support VT_DECIMAL as output.

#include <stdarg.h>
Check for MAXFLOAT if FLT_MAX isn't there.
1998-12-15 14:01:21 +01:00
Modify widl to put the C COM macros inside an #ifdef COBJMACROS block as is done in the Windows headers. Add #define COBJMACROS where needed in Wine. Fixes the compilation of the oleaut32/tests/olefont.c and urlmon/tests/url.c conformance tests with the Windows headers.
2004-08-11 21:43:45 +02:00
#define COBJMACROS
Define NONAMELESS{STRUCT,UNION} explicitly in the files that need them.

* - VT_CLSID is a valid type type for pvargSrc, but not for pvargDest.
* - For by-value non-intrinsic types, a deep copy is made, i.e. The whole value
* is copied rather than just any pointers to it.
* - For by-value object types the object pointer is copied and the objects
* reference count increased using IUnknown_AddRef().
* - For all by-reference types, only the referencing pointer is copied.

- VarAnd, VarCmp (Strings only), VarNot implemented. - VarParseNumFromStr/VarNumFromParseNum handle negative currency numbers. - More VarCmp support (Decimals and Dates). - Date support for VB time only (0.0->1.0), corrected some date rounding and calculation errors around variant dates and the system time. - Variant date support now round trips! (Date->Variant->Date) due to misuse of tm_mon (0..11 not 1..12). - Better pre-1899 support for dates in the SYSTEMTIME format. - VarBstrFromCy, VarCyFromStr implemented. - VarFormat partial implementation (currency and date support). - VarFormatFromTokens, VarTokenizeFormatString partial implementation as per w2k (dates only so far). - Better debugging when dumping variants, and some additional trace points to help debugging. - Fix to VarBstrCmp to handle null and empty string the same (as per w2k, different to msdn). - Fix return from VarDateFromUdate. - Correct definition of CY structure.

*
* Convert a NUMPARSE structure into a numeric Variant type.
*
* PARAMS
* pNumprs [I] Source for parsed number. cDig must be set to the size of rgbDig
* rgbDig [I] Source for the numbers digits
* dwVtBits [I] VTBIT_ flags from "oleauto.h" indicating the acceptable dest types
* pVarDst [O] Destination for the converted Variant value.
*
* RETURNS
* Success: S_OK. pVarDst contains the converted value.
* Failure: E_INVALIDARG, if any parameter is invalid.
* DISP_E_OVERFLOW, if the number is too big for the types set in dwVtBits.
*
* NOTES
* - The smallest favoured type present in dwVtBits that can represent the
* number in pNumprs without losing precision is used.
* - Signed types are preferrred over unsigned types of the same size.
* - Preferred types in order are: integer, float, double, currency then decimal.
* - Rounding (dropping of decimal points) occurs without error. See VarI8FromR8()
* for details of the rounding method.
* - pVarDst is not cleared before the result is stored in it.

- VarAnd, VarCmp (Strings only), VarNot implemented. - VarParseNumFromStr/VarNumFromParseNum handle negative currency numbers. - More VarCmp support (Decimals and Dates). - Date support for VB time only (0.0->1.0), corrected some date rounding and calculation errors around variant dates and the system time. - Variant date support now round trips! (Date->Variant->Date) due to misuse of tm_mon (0..11 not 1..12). - Better pre-1899 support for dates in the SYSTEMTIME format. - VarBstrFromCy, VarCyFromStr implemented. - VarFormat partial implementation (currency and date support). - VarFormatFromTokens, VarTokenizeFormatString partial implementation as per w2k (dates only so far). - Better debugging when dumping variants, and some additional trace points to help debugging. - Fix to VarBstrCmp to handle null and empty string the same (as per w2k, different to msdn). - Fix return from VarDateFromUdate. - Correct definition of CY structure.
