// cudaError_t and CUResult can both safely be cast to an unsigned int
static __thread unsigned int __SAFE_err;
// The very strange cast in these macros is to satisfy two goals at tension:
// 1. This file should be able to be included in non-CUDA-using files, and thus
// should use no CUDA types outside of this macro.
// 2. We want to typecheck uses of these macros. The driver and runtime APIs
// do not have identical error numbers and/or meanings, so runtime library
// calls should use SAFE, and driver library calls should use SAFE_D.
// These macros allow typechecking, but keep a generic global error variable.
