ITypeInfo::GetRefTypeOfImplType method
If a type description describes a COM class, it retrieves the type description of the implemented interface types. For an interface, GetRefTypeOfImplType returns the type information for inherited interfaces, if any exist.
Syntax
HRESULT GetRefTypeOfImplType(
[in] UINT index,
[out] HREFTYPE *pRefType
);
Parameters
- index [in]
-
The index of the implemented type whose handle is returned. The valid range is 0 to the cImplTypes field in the TYPEATTR structure.
- pRefType [out]
-
A handle for the implemented interface (if any). This handle can be passed to ITypeInfo::GetRefTypeInfo to get the type description.
Return value
This method can return one of these values.
| Return code | Description |
|---|---|
|
Success. |
|
One or more of the arguments is not valid. |
|
Passed index is outside the range 0 to 1 less than the number of function descriptions. |
Remarks
If the TKIND_DISPATCH type description is for a dual interface, the TKIND_INTERFACE type description can be obtained by calling GetRefTypeOfImplType with an indexof –1, and by passing the returned pRefTypehandle to GetRefTypeInfo to retrieve the type information.
