Thank you Anthony and Joe. I thought that all arguments should be passed into pointers. 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.

By passing the address of a double, you *are* passing a pointer.
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...
Cheers,
Mark
