Thank you Mark. That is exactly what my problem was.If the example included parsed integer and/or float (double) variables it would be much desriptive

Thank you Anthony and Joe. I thought that all arguments should be passed into pointers.
By passing the address of a double, you *are* passing a pointer.
The introductary example in the python reference documentation about Python extension confused me. I hope that the mentioned example will be changed to something simpler.
Which specific example did you find confusing? I'm guessing the 'spam' example at http://docs.python.org/ext/simpleExample.html, as it does:
const char *command; int sts; if (!PyArg_ParseTuple(args, "s", &command)) return NULL;
and strings are somewhat "special", in that a pointer is the "native" type of a string, so a pointer to a pointer is indeed what is passed. If that example also parsed an integer it might have made things a little clearer..
