WHvGetVirtualProcessorInterruptControllerState

Retrieves the state of a virtual processor's interrupt controller.

Important

WHvGetVirtualProcessorInterruptControllerState is deprecated. Use WHvGetVirtualProcessorState with the WHvVirtualProcessorStateTypeInterruptControllerState2 state type instead.

Note

This function applies to x64 partitions only.

Syntax

HRESULT
WINAPI
WHvGetVirtualProcessorInterruptControllerState(
    _In_ WHV_PARTITION_HANDLE Partition,
    _In_ UINT32 VpIndex,
    _Out_writes_bytes_to_(StateSize, *WrittenSize) VOID* State,
    _In_ UINT32 StateSize,
    _Out_opt_ UINT32* WrittenSize
    );

Parameters

Partition

Specifies the partition of the virtual processor.

VpIndex

Specifies the index of the virtual processor whose interrupt controller should be retrieved.

State

Specifies a buffer to write the interrupt controller state into.

StateSize

Specifies the size of the buffer, in bytes.

WrittenSize

If non-NULL, receives the number of bytes written to the buffer.

Return Value

If the function succeeds, the return value is S_OK.

If the buffer is too small to contain the interrupt controller state, the return value is WHV_E_INSUFFICIENT_BUFFER. In this case, WrittenSize receives the number of bytes necessary to fit the interrupt controller state.

Remarks

The WHvGetVirtualProcessorInterruptControllerState function retrieves the state of the specified virtual processor's interrupt controller.
