HRESULT
WINAPI
WHvRunVirtualProcessor(
    _In_ WHV_PARTITION_HANDLE Partition,
    _In_ UINT32 VpIndex,
    _Out_writes_bytes_(ExitContextSizeInBytes) VOID* ExitContext,
    _In_ UINT32 ExitContextSizeInBytes
    );

Parameters

Partition

handle 轉到 partition 物件。

VpIndex

指定執行的虛擬處理器的索引。

ExitContext

指定接收上下文結構的輸出緩衝區，提供導致 WHvRunVirtualProcessor 函式回傳原因的資訊。

ExitContextSizeInBytes

指定接收出口上下文的緩衝區大小，單位為位元組。

傳回值

如果函式成功，則傳回值為 S_OK。

Remarks

透過呼叫函 WHvRunVirtualProcessor 式來執行虛擬處理器（即啟用來賓程式碼）。 呼叫會同步阻塞，直到虛擬處理器執行虛擬化堆疊必須處理的操作（例如存取未映射或無法存取的 GPA 空間記憶體）或虛擬化堆疊明確請求該函式的退出（例如，注入中斷給虛擬處理器或變更虛擬機狀態）。
