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

Parameters

Partition

Menentukan partisi yang akan diinterupsi.

Interrupt

Menentukan karakteristik dan tujuan interupsi.

InterruptControlSize

Menentukan ukuran Interrupt, dalam byte.

Mengembalikan Nilai

Jika fungsi berhasil, nilai yang dikembalikan adalah S_OK.

Remarks

Fungsi WHvRequestInterrupt meminta agar interupsi yang dijelaskan oleh WHV_INTERRUPT_CONTROL struktur dikirimkan ke partisi.
