[O] Capturing output from C/C++

[Roger Mason]

Hello,

I have a short C++ program:

#+BEGIN_SRC cpp :flags -lm :results output
#include <iostream>
#include <fstream>
#include <cmath>                // for ceil
#include <cstdlib>              // for atof

  double f (double fv, double o, int i) {
    return fv / 2.0 + (1.0 - o) * fv * i;
  }

int num (double d, double fv, double o) {
  return (int)ceil( d / ((1.0 - o) * fv ));
  }

int main (int argc, char* argv[]) {
    if ( argc < 6 ) {
      std::cout << "Usage:\n" << std::endl;
      std::cout << "grid w fovx ox h fovy oy\n" << std::endl;
      return 1;
    }
...
#+END_SRC

that outputs some data to stdout.

So far I have not been able to capture the output of the program back
into to my org buffer.

Is that possible and, if so, how?

Thanks,
Roger
