Function rcudnn::cudaPeekAtLastError

pub unsafe extern "C" fn cudaPeekAtLastError() -> cudaError

\brief Returns the last error from a runtime call

Returns the last error that has been produced by any of the runtime calls in the same host thread. Note that this call does not reset the error to ::cudaSuccess like ::cudaGetLastError().
