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.

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.

Requirements

Header	oaidl.h, oaidl.idl
Library	oleaut32.lib, uuid.lib
