Message

SYCL uses exceptions to report errors and does not use the error codes. The original code was commented out and a warning string was inserted. You need to rewrite this code.

Detailed Help

SYCL* uses exceptions to report errors and does not use error codes. The original code tries to get a string message through the error code, while SYCL does not require such functionality.

To indicate that the code needs to be updated, a warning string is inserted.

Suggestions to Fix

You may need to rewrite this code.

For example, this original CUDA* code:

void foo() {
  float *f;
  cudaError_t err = cudaMalloc(&f, 4);
  printf("%s\n", cudaGetErrorString(err));
}

results in the following migrated SYCL code:

void foo()
  float *f;
  int err = (f = (float *)sycl::malloc_device(4, dpct::get_default_queue()), 0);
  /*
  DPCT1009:1: SYCL uses exceptions to report errors and does not use the error
  codes. The original code was commented out and a warning string was inserted.
  You need to rewrite this code.
  */
  printf("%s\n",
         "cudaGetErrorString is not supported" /*cudaGetErrorString(err)*/);
}

which is rewritten to:

void foo() {
  float *f;
  try {
    f = (float *)sycl::malloc_device(4, dpct::get_default_queue())
  } catch (sycl::exception const &e) {
    std::cerr << e.what() << std::endl;
  }
}
