CUresult cuGraphicsUnmapResources ( unsigned int  count, CUgraphicsResource *  resources, CUstream  hStream   ) Unmaps the count graphics resources in resources. Once unmapped, the resources in resources may not be accessed by CUDA until they are mapped again. This function provides the synchronization guarantee that any CUDA work issued in stream before cuGraphicsUnmapResources() will complete before any subsequently issued graphics work begins. If resources includes any duplicate entries then CUDA_ERROR_INVALID_HANDLE is returned. If any of resources are not presently mapped for access by CUDA then CUDA_ERROR_NOT_MAPPED is returned. Parameters: count  - Number of resources to unmap resources  - Resources to unmap hStream  - Stream with which to synchronize Returns: CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_HANDLE, CUDA_ERROR_NOT_MAPPED, CUDA_ERROR_UNKNOWN Note: Note that this function may also return error codes from previous, asynchronous launches.
