ITypeInfo::GetRefTypeInfo method (oaidl.h)

  • Article

If a type description references other type descriptions, it retrieves the referenced type descriptions.

Syntax

HRESULT GetRefTypeInfo(
  [in]  HREFTYPE  hRefType,
  [out] ITypeInfo **ppTInfo
);

Parameters

[in] hRefType

A handle to the referenced type description to return.

[out] ppTInfo

The referenced type description.

Return value

This method can return one of these values.

Return code Description
S_OK
Success.
E_INVALIDARG
One or more of the arguments is not valid.
E_OUTOFMEMORY
Insufficient memory to complete the operation.

Remarks

On return, the second parameter contains a pointer to a pointer to a type description that is referenced by this type description. A type description must have a reference to each type description that occurs as the type of any of its variables, function parameters, or function return types. For example, if the type of a data member is a record type, the type description for that data member contains the hRefType of a referenced type description. To get a pointer to the type description, the reference is passed to GetRefTypeInfo.
