IErrorInfo::GetGUID

  • Статья

Returns the GUID of interface that defined the error.

Syntax

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.
