Return Value

The return value obtained from the returned HRESULT is one of the following:

Return value	Meaning

Comments

ICreateErrorInfo::SetGUID sets the GUID of the interface that defined the error. If the error was defined by the system, set ICreateErrorInfo::SetGUID to GUID_NULL.

This GUID does not necessarily represent the source of the error; however, the source is the class or application that raised the error. Using the GUID, applications can handle errors in an interface, independent of the class that implements the interface.

Example

hr = CreateErrorInfo(&pcerrinfo);
pcerrinfo->SetGUID(IID_IHello);
