204 Module Documentation The Flags argument may be used to specify additional parameters at register time. The only valid value for this parameter is • CU_GRAPHICS_REGISTER_FLAGS_NONE Not all Direct3D resources of the above types may be used for interoperability with CUDA. The following are some limitations. • The primary rendertarget may not be registered with CUDA. • Resources allocated as shared may not be registered with CUDA. • Textures which are not of a format which is 1, 2, or 4 channels of 8, 16, or 32-bit integer or floating-point data cannot be shared. • Surfaces of depth or stencil formats cannot be shared. If Direct3D interoperability is not initialized for this context using cuD3D9CtxCreate then CUDA_ERROR_- INVALID_CONTEXT is returned. If pD3DResource is of incorrect type or is already registered then CUDA_- ERROR_INVALID_HANDLE is returned. If pD3DResource cannot be registered then CUDA_ERROR_- UNKNOWN is returned. If Flags is not one of the above specified value then CUDA_ERROR_INVALID_VALUE is returned. Parameters: pCudaResource - Returned graphics resource handle pD3DResource - Direct3D resource to register Flags - Parameters for resource registration Returns: 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_UNKNOWN See also: Note that this function may also return error codes from previous, asynchronous launches. cuD3D9CtxCreate, cuGraphicsUnregisterResource, cuGraphicsMapResources, cuGraphicsSubResourceGetMappedArray, cuGraphicsResourceGetMappedPointer Generated for NVIDIA CUDA Library by Doxygen
