Swig and Python

[Java and Swing]

I am trying to wrap some C code I have.  Currently I have something
like...

defs.h
-----------
typedef unsigned long MY_DIGIT;

myapp.c
-------------
void MakeDigits(MY_DIGIT digits[]) {
    ....
}

char* GetString(char *inMessage, MY_DIGIT *digit) {
    char *results;
    ...
    ...
    return results;
}


...ok so my interface for swig looks like..

%module MyApp
%{
    #include "math.h"
%}

extern void MakeDigits(MY_DIGIT digits[]);
extern char* GetString(char *inMessage, MY_DIGIT *digit);

%include "cpointer.i"
%pointer_functions(MY_DIGIT, digit_array);

%include "cmalloc.i"
%malloc(int);
%free(int);

...Ok, so I have a couple questions.
1)  How would I call MakeDigits from python?  In the C code I would
normally have something like...
        MY_DIGIT tmp[10];
        MakeDigits(tmp);

2)  How would I call GetString?  Again, in C I would have...
        char *ptr;
        char msg[100] = "Hello World";
        MY_DIGIT x = 98;
        ptr = GetString(msg, x);

3) Did I define MY_DIGIT correctly in my SWIG interface file?

4) If I try the following Python code...
        x = new_digit_array()
        print x
   then Python.exe dies...any idea?

thanks for the help.  I am trying to find my answers int he SWIG
docs...either i haven't found it or I didn't understand when I came
across it.

thanks in the mean time.
