Syntax

HRESULT
WINAPI
WHvGetVirtualProcessorXsaveState(
    _In_ WHV_PARTITION_HANDLE Partition,
    _In_ UINT32 VpIndex,
    _Out_writes_bytes_to_(BufferSizeInBytes, *BytesWritten) VOID* Buffer,
    _In_ UINT32 BufferSizeInBytes,
    _Out_ UINT32* BytesWritten
    );

Parameters

Partition

Specifies the partition of the virtual processor.

VpIndex

Specifies the index of the virtual processor whose XSAVE state should be queried.

Buffer

Specifies the buffer to receive the virtual processor's XSAVE state.

BufferSizeInBytes

Specifies the size of the buffer, in bytes.

BytesWritten

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 not large enough, the return value is WHV_E_INSUFFICIENT_BUFFER. In this case, BytesWritten receives the required buffer size.
