Re: [Boost-users] [python] Passing pointers as arguments without copying.

I don't know about the whole boost::noncopyable, but if you dont want to pass a copy of the class, doesn't a reference/pointer do th trick?

I don't know how to do it.

I mean, I try to expose the class

class_ ...;

class_("MyClass", ...). def(&MyClass::f, "f");

The problem is that "f", exposed to python, takes an argument of type MyClass2 *.

But MyClass2 * is noncopyable. So I cannot expose f that way because python will try to copy *myclass2 and it's noncopyable.

How can I avoid that copying? I don't know how. I saw something with ptr(), but it was to take a function with parameters from python to c++, not the other way, which is what I'm trying.

If it takes MyClass2*, then it will pass the memory address to it, it should not copy it...
