Function cuStreamQuery

pub unsafe extern "C" fn cuStreamQuery(hStream: CUstream) -> CUresult

\brief Determine status of a compute stream

Returns ::CUDA_SUCCESS if all operations in the stream specified by \p hStream have completed, or ::CUDA_ERROR_NOT_READY if not.

For the purposes of Unified Memory, a return value of ::CUDA_SUCCESS is equivalent to having called ::cuStreamSynchronize().
