ITypeInfo::GetRefTypeOfImplType (Compact 2013)

3/26/2014

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.
