Embedding Python app in c app

I am on integration of a c library to python application. and i need to pass a list of variables from python size to a wrapper of C lib(which i am calling) just for understanding, i have written a small program:
After loading shared lib in python app. In Python side: 

 c_args = [5,6]
 PyPrintVal(c_args)

In C side:

PyPrintVal(PyObject *c_args)
{
       int i=0;
       int j=0;
       printf("In eINoiseRemoval\n");
       if (!PyArg_ParseTuple(c_args, "ii", &i,&j))
       {      fprintf(stderr, "error in parsing\n");
              return -1;
       }
       printf(i1=%d   j=%d\n, i,j)
}

then I am getting segmentation fault ? Is there anything left?
for that i am looking http://docs.python.org/2/extending/extending.html#a-simple-example

but not getting any answer. Thanks

You can use gdb to find out exactly where this segfault is:

$ gdb python
......
> set args my_python_script.py
> run
.......
Segmentation Fault
> where

This will give you a stack trace and point you to the exact location of the segfault.
