Method Interface for a Segment Method

Parameter types for the segment method are shown in this table:

Parameter Type	In Parameter	Out or InOut Parameter
String	BSTR	BSTR*
Wide String	BSTR	BSTR*
Number	DECIMAL	DECIMAL*
Signed Number	DECIMAL	DECIMAL*
Date	DATE	DATE*
Boolean	VARIANT_BOOL	VARIANT_BOOL*

For example, if you had a segment method called PublicMethod which has an in parameter of each type and an in/out parameter of each type, this is how that method would be generated into the IDL file.

HRESULT PublicMethod([in]     BSTR           _sg_StringIn,
[in]     BSTR           _sg_WideStringIn,
[in]     DECIMAL        _sg_NumberIn,
[in]     DECIMAL        _sg_SignedNumberIn,
[in]     DATE           _sg_DateIn,
[in]     VARIANT_BOOL   _sg_BooleanIn,
[in,out] BSTR *         _sg_StringInOut,
[in,out] BSTR *         _sg_WideStringInOut,
[in,out] DECIMAL *      _sg_NumberInOut,
[in,out] DECIMAL *      _sg_SignedNumberInOut,
[in,out] DATE *         _sg_DateInOut,
[in,out] VARIANT_BOOL * _sg_BooleanInOut);
