I can implement my function in C++, using features in C++.

As a simple example:
extern "C" void sort_doubles(double array[],int count)
{
   std::sort(array,array+count);
}

Want some easy standardised parallelism?

/// Untested - I may have got the lambda syntax wrong
extern "C" double sum_array_parallel(const double array[], int count)
{
  std::future<double> fut =
     std::async(std::launch::async,
                [array,count](){
                        return std::accumulate(array,array+count/2,0.);
                });
  double last = std::accumulate(array+count/2,array+count,0.);
  return last + fut.get();
}

I'm sure Jacob will be here shortly to tell you that the latter would be
simpler and far more readable if I did it with C11 threads.
