HRESULT
WINAPI
WHvRequestInterrupt(
    _In_ WHV_PARTITION_HANDLE Partition,
    _In_ const WHV_INTERRUPT_CONTROL* Interrupt,
    _In_ UINT32 InterruptControlSize
    );

Parameters

Partition

Specifica la partizione da interrompere.

Interrupt

Specifica le caratteristiche e la destinazione dell'interrupt.

InterruptControlSize

Specifica le dimensioni di Interrupt, in byte.

Valore restituito

Se la funzione ha esito positivo, il valore restituito è S_OK.

Remarks

La WHvRequestInterrupt funzione richiede che un interrupt descritto dalla WHV_INTERRUPT_CONTROL struttura venga recapitato alla partizione.
