D3DKMT_OPENRESOURCEFROMNTHANDLE structure

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.

Syntax


typedef struct _D3DKMT_OPENRESOURCEFROMNTHANDLE {
  D3DKMT_HANDLE              hDevice;
  HANDLE                     hNtHandle;
  UINT                       NumAllocations;
  D3DDDI_OPENALLOCATIONINFO2 *pOpenAllocationInfo2;
  UINT                       PrivateRuntimeDataSize;
  VOID                       *pPrivateRuntimeData;
  UINT                       ResourcePrivateDriverDataSize;
  VOID                       *pResourcePrivateDriverData;
  UINT                       TotalPrivateDriverDataBufferSize;
  VOID                       *pTotalPrivateDriverDataBuffer;
  D3DKMT_HANDLE              hResource;
  D3DKMT_HANDLE              hKeyedMutex;
  VOID                       *pKeyedMutexPrivateRuntimeData;
  UINT                       KeyedMutexPrivateRuntimeDataSize;
  D3DKMT_HANDLE              hSyncObject;
} D3DKMT_OPENRESOURCEFROMNTHANDLE;

Members

hDevice

[in] A D3DKMT_HANDLE data type that represents the device.

hNtHandle

[in] An NT handle to the process.

NumAllocations

[in] The number of allocations associated with the resource.

pOpenAllocationInfo2

[in] This member is reserved and should be set to zero.

PrivateRuntimeDataSize

[in] The size, in bytes, of the buffer pointed to by the pPrivateRuntimeData member.

pPrivateRuntimeData

[in] A caller-supplied buffer where the runtime private data associated with this resource will be copied to.

ResourcePrivateDriverDataSize

[in] The size, in bytes, of the buffer pointed to by the pResourcePrivateDriverData member.

pResourcePrivateDriverData

[in] A caller-supplied buffer where the driver private data associated with the resource will be copied to.

TotalPrivateDriverDataBufferSize

[in] The size, in bytes, of the buffer pointed to by the pTotalPrivateDriverDataBuffer member.

[out] The size, in bytes, of the data written to pTotalPrivateDriverDataBuffer.

pTotalPrivateDriverDataBuffer

[in] A pointer to a caller-supplied buffer where the driver private data will be stored.

hResource

[out] A handle to the resource in this process.

hKeyedMutex

[out] A handle to the keyed mutex in this process.

pKeyedMutexPrivateRuntimeData

[in] A buffer that contains initial private data.

The data in this buffer will be copied only if the keyed mutex does not already have private data.

If this member has a value of NULL, the value of the KeyedMutexPrivateRuntimeDataSize member must be zero.

KeyedMutexPrivateRuntimeDataSize

[in] The size, in bytes, of the buffer pointed to by the pKeyedMutexPrivateRuntimeData member.

hSyncObject

[out] A handle to the synchronization object in this process.
