Syntax
HRESULT GetRefTypeOfImplType(unsigned int index,
HREFTYPE FAR* pRefType );
Parameters
index
Index of the implemented type whose handle is returned. The valid range is 0 to the cImplTypes member in the TYPEATTR structure.
pRefType
On return, pointer to a handle for the implemented interface (if any). This handle can be passed to ITypeInfo::GetRefTypeInfo to get the type description.
Return Values
One of the values described in the following table is returned.
| Value | Description |
| S_OK | Success. |
| TYPE_E_ELEMENTNOTFOUND | Passed index is outside the range 0 to 1 less than the number of function descriptions. |
| E_INVALIDARG | One or more of the parameters is invalid. |
| TYPE_E_IOERROR | The function could not read from the file. |
| TYPE_E_INVDATAREAD | Invalid data. |
| TYPE_E_UNSUPFORMAT | The type library has an older format. |
| TYPE_E_INVALIDSTATE | The type library could not be opened. |
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 index of –1, and by passing the returned pRefType handle to GetRefTypeInfo to retrieve the type information.
