Interfacing C and Python [duplicate]

Question

Possible Duplicate:
Calling C/C++ from python?

I am looking to bridge a C++ and python code.

The interfaces needed by python code are :

floatvect(): this one should return an empty float vector (basically a list)

get_quant(input_list_2, self.m_state_num, self.m_qm_vector)

The corresponding C++ function is :

int equalwidth_quant(int target_num_state, FloatVec &raw_data, FloatVec &init_quant)

When my python code contacts get_quant, it should be able to call the corresponding C++ function and get the result. The result is basically stored in the last attribute of that C++ function.

Is there any specific libraries which I can use for achieving this?

int equalwidth_quant(int target_num_state, FloatVec &raw_data, FloatVec &init_quant) That's not a C function. — Flavius

I'm thinking he wants to call equalwidth_quant from inside of get_quant. Then again, it's entirely impossible to figure out what's really supposed to be going on here. — Ken Wayne VanderLinde

You need to write equalwidth_quant as a C-extension for Python. Check out Cython or here's a simple tutorial.

I don't even think you deserve these down votes since the problem is actually in the question.
