This method retrieves the type description of implemented interface types for a component object class (coclass) or an inherited interface.
Syntax
HRESULT GetRefTypeOfImplType(
unsigned int index,
HREFTYPE FAR* pRefType
);
Parameters
- index
[in] Index of the implemented type whose handle is returned. The valid range is 0 to the cImplTypes member in the TYPEATTR structure.
- pRefType
[out] 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 Value
The following table shows the return values for this function.
| Value | Description |
|---|---|
S_OK |

TYPE_E_ELEMENTNOTFOUND |
Passed index is outside the range 0 to 1 less than the number of function descriptions. |
