Here's a very simple program where I want to get back out
(PyArg_ParseTuple) what I put in (Py_BuildValue) - however, I can't seem
to do that. Can someone PLEASE enlighten me?
thanks,

#include "Python.h"
main(argc, argv)
int argc;
char **argv;
{
unsigned char ba[3] = {2,4,8}; /* byte array */
PyObject *pobj;
char *cstr;
int len;
Py_Initialize();
printf("Py_BuildValue of %d %d %d\n",ba[0],ba[1],ba[2]);
pobj = Py_BuildValue("s#", ba,3);
if (pobj == (PyObject *)NULL)
printf("pobj is NULL\n");
printf("\nPyArg_ParseTuple(pobj,...)\n" );
PyArg_ParseTuple(pobj,"s#", &cstr,&len);
printf("len=%d\n",len);
printf("cstr=%s\n",cstr);
printf("cstr[0]=%c\n",cstr[0]);
printf("cstr[1]=%c\n",cstr[1]);
printf("cstr[2]=%c\n",cstr[2]);
printf("(int)cstr[0]=%d\n",(int)cstr[0]);
printf("(int)cstr[1]=%d\n",(int)cstr[1]);
printf("(int)cstr[2]=%d\n",(int)cstr[2]);
}
