IErrorInfo::GetGUID method (oaidl.h)

  • Article

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

Syntax

HRESULT GetGUID(
  [out] GUID *pGUID
);

Parameters

[out] pGUID

A pointer to a GUID, or GUID_NULL, if the error was defined by the operating system.

Return value

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

IErrorInfo::GetGUID returns the GUID of the interface that defined the error. If the error was defined by the system, IErrorInfo::GetGUID returns GUID_NULL.

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.
