IErrorInfo::GetGUID (Compact 2013)

  • Artigo

3/26/2014

This method returns the globally unique identifier (GUID) of the interface that defined the error.

Syntax

HRESULT GetGUID( 
  GUID* pGUID 
);

Parameters

  • pGUID
    [out] Pointer to a GUID, or GUID_NULL, if the error was defined by the operating system.

Return Value

If the method succeeds, the return value is S_OK.

Remarks

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