D3DKMT_OPENRESOURCEFROMNTHANDLE structure (d3dkmthk.h)
Describes information that is required to open a shared resource from an NT handle to the process. The shared resource can be a set of allocations, a keyed mutex, or a synchronization object.

[in] D3DKMT_HANDLE hDevice;
[in] HANDLE hNtHandle;
[in] UINT NumAllocations;
[in] D3DDDI_OPENALLOCATIONINFO2 *pOpenAllocationInfo2;
[in] UINT PrivateRuntimeDataSize;
[in] VOID *pPrivateRuntimeData;
[in] UINT ResourcePrivateDriverDataSize;

Members
[in] hDevice
A D3DKMT_HANDLE data type that represents the device.
[in] hNtHandle
An NT handle to the process.
[in] NumAllocations
The number of allocations associated with the resource.
[in] pOpenAllocationInfo2
This member is reserved and should be set to zero.
[in] PrivateRuntimeDataSize
The size, in bytes, of the buffer pointed to by the pPrivateRuntimeData member.
[in] pPrivateRuntimeData
A caller-supplied buffer where the runtime private data associated with this resource will be copied to.
[in] ResourcePrivateDriverDataSize
The size, in bytes, of the buffer pointed to by the pResourcePrivateDriverData member.
[in] pResourcePrivateDriverData
A caller-supplied buffer where the driver private data associated with the resource will be copied to.
[in] TotalPrivateDriverDataBufferSize
The size, in bytes, of the buffer pointed to by the pTotalPrivateDriverDataBuffer member.
[out] The size, in bytes, of the data written to pTotalPrivateDriverDataBuffer.
[in] pTotalPrivateDriverDataBuffer
A pointer to a caller-supplied buffer where the driver private data will be stored.
[out] hResource
A handle to the resource in this process.
[out] hKeyedMutex
A handle to the keyed mutex in this process.
pKeyedMutexPrivateRuntimeDat
[in] KeyedMutexPrivateRuntimeDataSize
The size, in bytes, of the buffer pointed to by the pKeyedMutexPrivateRuntimeData member.
[out] hSyncObject
A handle to the synchronization object in this process.
