Redirecting STDIO/STDERR in an python embedded application

I am trying to redirect Pythons STDIO/STDERR within my application. Here
is the python code:
PyRun_SimpleString("class my_stdout:\n"
" def write(self,string):\"
" image.stdout(string)\n"
"import sys\n"
"sys.stdout = my_stdout()\n");
And here is the C++ code:
static struct _object *s_stdout(PyObject *self, PyObject *args)
{
char *string = NULL;
if (!PyArg_ParseTuple(args, "s" &string))
return Py_None;
/* some code
return Py_None
}
The function s_stdout is being called but PyArg_ParseTuple is failing. I
believe it doesn't think there is a string in the "args" Object. When I
look at the "args" object, it claims it is a "string" but I don't
actually see any text associated with it, other than "string." Any
ideas?
