Sets the globally unique identifier (GUID) of the interface that defined the error.

HRESULT SetGUID(
[in] REFGUID rguid
);
Parameters

The GUID of the interface that defined the error, or GUID_NULL if the error was defined by the operating system.
Return value

| Return code | Description |
|---|---|
|
Success. |
|
Insufficient memory to complete the operation. |
Remarks
This method 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.
Use of this function is demonstrated in the file Main.cpp of the COM Fundamentals Hello sample.
