ICreateTypeInfo::AddRefTypeInfo method (oaidl.h)

  • Article

Adds a type description to those referenced by the type description being created.

Syntax

HRESULT AddRefTypeInfo(
  [in] ITypeInfo *pTInfo,
  [in] HREFTYPE  *phRefType
);

Parameters

[in] pTInfo

The type description to be referenced.

[in] phRefType

The handle that this type description associates with the referenced type information.

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.
E_ACCESSDENIED
 Cannot write to the destination.
STG_E_INSUFFICIENTMEMORY
Insufficient memory to complete the operation.
TYPE_E_WRONGTYPEKIND
 Type mismatch.

Remarks

The second parameter returns a pointer to the handle of the added type information. If AddRefTypeInfo has been called previously for the same type information, the index that was returned by the previous call is returned in phRefType. If the referenced type description is in the type library being created, its type information can be obtained by calling IUnknown::QueryInterface(IID_ITypeInfo, ...) on the ICreateTypeInfo interface of that type description.
