Name	Description
ISupportErrorInfoImpl::InterfaceSupportsErrorInfo	Indicates whether the interface identified by riid supports the IErrorInfo interface.

Remarks

The ISupportErrorInfo Interface ensures that error information can be returned to the client. Objects that use IErrorInfo must implement ISupportErrorInfo.

Class ISupportErrorInfoImpl provides a default implementation of ISupportErrorInfo and can be used when only a single interface generates errors on an object. For example:

class ATL_NO_VTABLE CMySuppErrClass :
   public CComObjectRootEx<CComSingleThreadModel>,
   public CComCoClass<CMySuppErrClass, &CLSID_MySuppErrClass>,
   public ISupportErrorInfoImpl<&IID_IMySuppErrClass>,
   public IDispatchImpl<IMySuppErrClass, &IID_IMySuppErrClass, &LIBID_NVC_ATL_COMLib, /*wMajor =*/ 1, /*wMinor =*/ 0>
