Error String for cufft?

Accelerated Computing CUDA CUDA Programming and Performance

I can’t find the cudaGetErrorString(e) function counterpart for cufft. Is it available or not?
So when I got any cufftResult from the FFT execution, I can’t really get a descriptive message, unless if I refer back to the cufft.h file.
But I would like something that is robust enough for future updates (instead of a hard-coded error message).
Note that the CUFFT manual that I just downloaded from the Cuda page has some mistakes in the error messages (for cufftExec***), e.g. the CUFFT_UNALIGNED_DATA error is not available anymore.

nobody knows anything about the error strings in CUFFT?

Have a look at [samples inst dir]/common/inc/helper_cuda.h

Here you will find:

#ifdef _CUFFT_H_
// cuFFT API errors
static const char *_cudaGetErrorEnum(cufftResult error)
{
    switch (error)
    {
        case CUFFT_SUCCESS:
            return "CUFFT_SUCCESS";

        case CUFFT_INVALID_PLAN:
            return "CUFFT_INVALID_PLAN";

        case CUFFT_ALLOC_FAILED:
            return "CUFFT_ALLOC_FAILED";

        case CUFFT_INVALID_TYPE:
            return "CUFFT_INVALID_TYPE";

        case CUFFT_INVALID_VALUE:
            return "CUFFT_INVALID_VALUE";

        case CUFFT_INTERNAL_ERROR:
            return "CUFFT_INTERNAL_ERROR";

        case CUFFT_EXEC_FAILED:
            return "CUFFT_EXEC_FAILED";

        case CUFFT_SETUP_FAILED:
            return "CUFFT_SETUP_FAILED";

        case CUFFT_INVALID_SIZE:
            return "CUFFT_INVALID_SIZE";

        case CUFFT_UNALIGNED_DATA:
            return "CUFFT_UNALIGNED_DATA";
    }

    return "<unknown>";
}
#endif
