62 Module DocumentationReturns:Note:See also:cudaSuccess, cudaErrorInvalidValue, cudaErrorInvalidResourceHandle,Note that this function may also return error codes from previous, asynchronous launches.cudaD3D9GetDevice, cudaD3D9SetDirect3DDevice, cudaD3D9GetDirect3DDevice, cudaD3D9RegisterResource,cudaD3D9UnregisterResource, cudaD3D9MapResources, cudaD3D9UnmapResources,cudaD3D9ResourceSetMapFlags, cudaD3D9ResourceGetMappedArray, cudaD3D9ResourceGetMappedPointer,cudaD3D9ResourceGetMappedSize, cudaD3D9ResourceGetMappedPitch3.10.3.10 cudaError_t cudaD3D9ResourceSetMapFlags (IDirect3DResource9 ∗ pResource, unsigned intflags)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:• cudaD3D9MapFlagsNone: Specifies no hints about how this resource will be used. It is therefore assumed thatthis resource will be read from and written to by CUDA kernels. This is the default value.• cudaD3D9MapFlagsReadOnly: Specifies that CUDA kernels which access this resource will not write to thisresource.• cudaD3D9MapFlagsWriteDiscard: Specifies that CUDA kernels which access this resource will not read fromthis resource and will write over the entire contents of the resource, so none of the data previously stored in theresource will be preserved.If pResource has not been registered for use with CUDA, then cudaErrorInvalidResourceHandle is returned. IfpResource is presently mapped for access by CUDA, then cudaErrorUnknown is returned.Parameters:pResource - Registered resource to set flags forflags - Parameters for resource mappingReturns:Note:See also:cudaSuccess, cudaErrorInvalidValue, cudaErrorInvalidResourceHandle, cudaErrorUnknownNote that this function may also return error codes from previous, asynchronous launches.cudaD3D9GetDevice, cudaD3D9SetDirect3DDevice, cudaD3D9GetDirect3DDevice, cudaD3D9RegisterResource,cudaD3D9UnregisterResource, cudaD3D9MapResources, cudaD3D9UnmapResources,cudaD3D9ResourceGetSurfaceDimensions, cudaD3D9ResourceGetMappedArray,cudaD3D9ResourceGetMappedPointer, cudaD3D9ResourceGetMappedSize, cudaD3D9ResourceGetMappedPitchGenerated on Wed Apr 1 16:11:42 2009 for NVIDIA CUDA Library by Doxygen
3.10 Direct3D 9 Interoperability 633.10.3.11 cudaError_t cudaD3D9SetDirect3DDevice (IDirect3DDevice9 ∗ pDxDevice)Records pDxDevice as the Direct3D device to use for Direct3D interoperability on this host thread. In order touse Direct3D interoperability, this call must be made before any non-device management CUDA runtime calls on thisthread. In that case, this call will return cudaErrorSetOnActiveProcess.Successful context creation on pDxDevice will increase the internal reference count on pDxDevice. This referencecount will be decremented upon destruction of this context through cudaThreadExit().Parameters:pDxDevice - Direct3D device to use for this threadReturns:Note:See also:cudaSuccess, cudaErrorInitializationError, cudaErrorInvalidValue, cudaErrorSetOnActiveProcessNote that this function may also return error codes from previous, asynchronous launches.cudaD3D9GetDevice, cudaD3D9GetDirect3DDevice, cudaD3D9RegisterResource, cudaD3D9UnregisterResource,cudaD3D9MapResources, cudaD3D9UnmapResources,cudaD3D9ResourceGetSurfaceDimensions, cudaD3D9ResourceSetMapFlags, cudaD3D9ResourceGetMappedArray,cudaD3D9ResourceGetMappedPointer, cudaD3D9ResourceGetMappedSize,cudaD3D9ResourceGetMappedPitch3.10.3.12 cudaError_t cudaD3D9UnmapResources (int count, IDirect3DResource9 ∗∗ ppResources)Unmaps the count Direct3D resources in ppResources.This function provides the synchronization guarantee that any CUDA kernels issued before cudaD3D9UnmapResources()will complete before any Direct3D calls issued after cudaD3D9UnmapResources()begin.If any of ppResources have not been registered for use with CUDA or if ppResources contains any duplicateentries, then cudaErrorInvalidResourceHandle is returned. If any of ppResources are not presently mapped foraccess by CUDA then cudaErrorUnknown is returned.Parameters:count - Number of resources to unmap for CUDAppResources - Resources to unmap for CUDAReturns:Note:See also:cudaSuccess, cudaErrorInvalidResourceHandle, cudaErrorUnknownNote that this function may also return error codes from previous, asynchronous launches.cudaD3D9GetDevice, cudaD3D9SetDirect3DDevice, cudaD3D9GetDirect3DDevice, cudaD3D9RegisterResource,cudaD3D9UnregisterResource, cudaD3D9MapResources,Generated on Wed Apr 1 16:11:42 2009 for NVIDIA CUDA Library by Doxygen
