178 Module Documentation• The primary rendertarget may not be registered with CUDA.• Resources allocated as shared may not be registered with CUDA.• Any resources allocated in D3DPOOL_SYSTEMMEM or D3DPOOL_MANAGED may not be registered withCUDA.• Textures which are not of a format which is 1, 2, or 4 channels of 8, 16, or 32-bit integer or floating-point datacannot be shared.• Surfaces of depth or stencil formats cannot be shared.If Direct3D interoperability is not initialized on this context, then CUDA_ERROR_INVALID_CONTEXT is returned.If pResource is of incorrect type (e.g. is a non-stand-alone IDirect3DSurface9) or is already registered,then CUDA_ERROR_INVALID_HANDLE is returned. If pResource cannot be registered then CUDA_ERROR_-UNKNOWN is returned.Parameters:pResource - Resource to register for CUDA accessflags - Flags for resource registrationReturns:Note:CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_-ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE, CUDA_ERROR_INVALID_HANDLE,CUDA_ERROR_OUT_OF_MEMORY, CUDA_ERROR_UNKNOWNSee also:Note that this function may also return error codes from previous, asynchronous launches.cuD3D9CtxCreate, cuD3D9GetDevice, cuD3D9GetDirect3DDevice, cuD3D9MapResources,cuD3D9ResourceGetMappedArray, cuD3D9ResourceGetMappedPitch, cuD3D9ResourceGetMappedPointer,cuD3D9ResourceGetMappedSize, cuD3D9ResourceGetSurfaceDimensions, cuD3D9ResourceSetMapFlags,cuD3D9UnmapResources, cuD3D9UnregisterResource3.28.2.6 CUresult cuD3D9ResourceGetMappedArray (CUarray ∗ pArray, IDirect3DResource9 ∗ pResource,U32 face, U32 level)Returns in ∗pArray an array through which the subresource of the mapped Direct3D resource pResourcewhich corresponds to face and level may be accessed. The value set in pArray may change every time thatpResource is mapped.If pResource is not registered then CUDA_ERROR_INVALID_HANDLE is returned. If pResource was notregistered with usage flags CU_D3D9_REGISTER_FLAGS_ARRAY then CUDA_ERROR_INVALID_HANDLE isreturned. If pResource is not mapped then CUDA_ERROR_NOT_MAPPED is returned.For usage requirements of face and level parameters, see cuD3D9ResourceGetMappedPointer().Parameters:pArray - Returned array corresponding to subresourcepResource - Mapped resource to accessGenerated on Wed Apr 1 16:11:42 2009 for NVIDIA CUDA Library by Doxygen

The values set in pPitch and pPitchSlice maychange every time that pResource is mapped.The pitch and Z-slice pitch values may be used to compute the location of a sample on a surface as follows.For a 2D surface, the byte offset of the sample at position x, y from the base pointer of the surface is:y ∗ pitch + (bytes per pixel) ∗ xFor a 3D surface, the byte offset of the sample at position x, y, z from the base pointer of the surface is:z∗ slicePitch + y ∗ pitch + (bytes per pixel) ∗ xBoth parameters pPitch and pPitchSlice are optional and may be set to NULL.If pResource is not of type IDirect3DBaseTexture9 or one of its sub-types or if pResource has not been registeredfor use with CUDA, then cudaErrorInvalidResourceHandle is returned. If pResource was not registeredwith usage flags CU_D3D9_REGISTER_FLAGS_NONE, then CUDA_ERROR_INVALID_HANDLE is returned. IfpResource is not mapped for access by CUDA then CUDA_ERROR_NOT_MAPPED is returned.For usage requirements of face and level parameters, see cuD3D9ResourceGetMappedPointer().Parameters:pPitch - Returned pitch of subresourcepPitchSlice - Returned Z-slice pitch of subresourcepResource - Mapped resource to accessface - Face of resource to accesslevel - Level of resource to accessReturns:CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_-ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE, CUDA_ERROR_INVALID_HANDLE,CUDA_ERROR_NOT_MAPPEDGenerated on Wed Apr 1 16:11:42 2009 for NVIDIA CUDA Library by Doxygen
