[C++-sig] global variable

[Stefan Fleiter]

Hi,

I am using pyste of boost.python to wrap a library.
This library has an init function 'init' which
allocates an object and sets a global pointer 'ptr' to
it. This function can only be called once, so 'ptr' can
or should never be changed.

1. How can I access 'ptr' or '*ptr'?
2. I have a function returning this 'ptr', what is the right
    call-Policy?

Many thanks,
Stefan
