Using printf in a C Extension

I am extending python with C and trying to debug with printf.   The code 
below succssfully returns the string "hello" when compiled and called, 
but the "can print from in here phrase" does not reach python stdout. 
Is there something screwy with my environment or is there some trick to 
this that I don't know.  Any help would be greatly appreciated!


#include <Python.h>

static PyObject*
helloworld(PyObject* self)
     printf("can print from in here?");
     return Py_BuildValue("s", "hello");

static char hw_docstr[] = "hello docstr";

static PyMethodDef hw_funcs[] = {
     {"helloworld", (PyCFunction)helloworld, METH_NOARGS, hw_docstr},

     Py_InitModule3("helloworld",hw_funcs, "simple module");
