IDebugBreakpointResolution2:: GetResolutionInfo
Ottiene le informazioni di risoluzione del punto di interruzione che descrivono questo punto di interruzione.
HRESULT GetResolutionInfo(
BPRESI_FIELDS dwFields,
BP_RESOLUTION_INFO* pBPResolutionInfo
);
int GetResolutionInfo(
enum BPRESI_FIELDS dwFields,
BP_RESOLUTION_INFO[] pBPResolutionInfo
);
Parametri
dwFields
[in] Una combinazione di flag BPRESI_FIELDS dall'enumerazione che determinano quali campi del parametro di pBPResolutionInfo devono essere compilati.pBPResolutionInfo
[out] BP_RESOLUTION_INFORMATION La struttura per riempire di informazioni su questo punto di interruzione.
Valore restituito
Se l'operazione riesce, restituisce S_OK; in caso contrario restituisce un codice di errore.
Esempio
Nell'esempio seguente viene implementato questo metodo per un oggetto semplice di CDebugBreakpointResolution che espone IDebugBreakpointResolution2 l'interfaccia.
