192 Module DocumentationIf pResource is not of type IDirect3DBaseTexture10 or IDirect3DSurface10 or if pResource has not been registeredfor use with CUDA, then CUDA_ERROR_INVALID_HANDLE is returned.For usage requirements of the SubResource parameter, see cuD3D10ResourceGetMappedPointer().Parameters:pWidth - Returned width of surfacepHeight - Returned height of surfacepDepth - Returned depth of surfacepResource - Registered resource to accessSubResource - Subresource of pResource to accessReturns:Note:CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_-ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE, CUDA_ERROR_INVALID_HANDLESee also:Note that this function may also return error codes from previous, asynchronous launches.cuD3D10CtxCreate, cuD3D10GetDevice, cuD3D10MapResources, cuD3D10RegisterResource,cuD3D10ResourceGetMappedArray, cuD3D10ResourceGetMappedPitch, cuD3D10ResourceGetMappedPointer,cuD3D10ResourceGetMappedSize, cuD3D10ResourceSetMapFlags, cuD3D10UnmapResources,cuD3D10UnregisterResource3.29.2.10 CUresult cuD3D10ResourceSetMapFlags (ID3D10Resource ∗ pResource, unsigned int Flags)Set flags for mapping the Direct3D resource pResource.Changes to flags will take effect the next time pResource is mapped. The Flags argument may be any of thefollowing.• CU_D3D10_MAPRESOURCE_FLAGS_NONE: Specifies no hints about how this resource will be used. It istherefore assumed that this resource will be read from and written to by CUDA kernels. This is the default value.• CU_D3D10_MAPRESOURCE_FLAGS_READONLY: Specifies that CUDA kernels which access this resourcewill not write to this resource.• CU_D3D10_MAPRESOURCE_FLAGS_WRITEDISCARD: Specifies that CUDA kernels which access thisresource will not read from this resource and will write over the entire contents of the resource, so none of thedata previously stored in the resource will be preserved.If pResource has not been registered for use with CUDA, then CUDA_ERROR_INVALID_HANDLE is returned.If pResource is presently mapped for access by CUDA then CUDA_ERROR_ALREADY_MAPPED is returned.Parameters:pResource - Registered resource to set flags forFlags - Parameters for resource mappingGenerated on Wed Apr 1 16:11:42 2009 for NVIDIA CUDA Library by Doxygen

If any of ppResources are not presently mappedfor access by CUDA, then CUDA_ERROR_NOT_MAPPED is returned.Parameters:count - Number of resources to unmap for CUDAppResources - Resources to unmap for CUDAReturns:Note:CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_-ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE, CUDA_ERROR_INVALID_HANDLE,CUDA_ERROR_NOT_MAPPED, CUDA_ERROR_UNKNOWNSee also:Note that this function may also return error codes from previous, asynchronous launches.cuD3D10CtxCreate, cuD3D10GetDevice, cuD3D10MapResources, cuD3D10RegisterResource,cuD3D10ResourceGetMappedArray, cuD3D10ResourceGetMappedPitch, cuD3D10ResourceGetMappedPointer,cuD3D10ResourceGetMappedSize, cuD3D10ResourceGetSurfaceDimensions, cuD3D10ResourceSetMapFlags,cuD3D10UnregisterResource3.29.2.12 CUresult cuD3D10UnregisterResource (ID3D10Resource ∗ pResource)Unregisters the Direct3D resource pResource so it is not accessible by CUDA unless registered again.If pResource is not registered, then CUDA_ERROR_INVALID_HANDLE is returned.Generated on Wed Apr 1 16:11:42 2009 for NVIDIA CUDA Library by Doxygen
