Return C++ class instance or pointer with clean memory?

[zliucd]

Hi all,

I wrote a C++ function that returns a class with its variables accessed by Python code. When returning a class instance pointer(with new operator), how to free the memory after Python calls the function? (As the memory for the class is used, it has to be manually freed.)

I also tried returning class instance (which is allocated on stack as a local variable), but C++ program got stuck...

Thanks.
