Thomas,
I guess this is the point where yo should start printf programing.
oh', already done :)
FWIW, Cython 0.14+ has special support for gdb now, so, in addition to
print and printf debugging, you can also use gdb to explore the state of
your application
hello,
Thomas, Gregory,
thank you for your ansrwers,

My module contains just 4 functions (in C), which translate 3rd
party lib to Python. The name would be _mycrypt.so example.
I wrapped it a pure Python module, its name is mycrypt.py.
Then, I've import pure Python module in a main program, like
this:

I've put it a Py_INCREF() after every PyModule_AddObject(), eg.:
PyModule_AddObject(o, "error", cibcrypt_error_nokey);
Py_INCREF(cibcrypt_error_nokey);
That looks correct, because PyModule_AddObject is documented as
stealing a reference to the object.
By the way,
hello,

I defined many exceptions:

static PyObject *cibcrypt_error_nofile;
static PyObject *cibcrypt_error_badpad;

switch(errcode) {

Another question: here is an another part ot my code:
static PyObject*
mycrypt_decrypt(PyObject *self, PyObject *args)
{
if (!PyArg_ParseTuple(args, "ss",&data,&path)) {
return NULL;
}
...
}

Dear Thomas,
thank you again,

Especially look at the concepts called "borrowed reference" vs. "owned
reference".
http://docs.python.org/extending/extending.html#reference-counting-in-python
will be quite helpful.

sorry for the typo, these are many "cibcrypt" reference, this is
