Returns the GUID of interface that defined the error.
HRESULT GetGUID ( GUID *pguid);
Parameters
- pguid
- [out] A pointer to memory in which to return the GUID of the interface that defined the error. If the error was defined by the operating system, the returned GUID is DB_NULLGUID. This is the same value as is returned in the iid element of the ERRORINFO structure returned by IErrorRecords::GetBasicErrorInfo.
Return Code
- S_OK
- The method succeeded.
- E_INVALIDARG
- pguid was a null pointer.
Comments
This GUID does not necessarily represent the source of the error; the source is the class or application that raised the error. Using the GUID, an application can handle errors in an interface independent of the class that implements the interface.
