I think you're mixing things up.
open() like you use it is a call to generate a python "file" object,
which is not the file descriptor a file_destructor_sink needs.
open() expects a string, but you offer a socket_pdu shared pointer (ie.
the python (swig) representation of the C++ block of that name).
I don't really understand what you are trying to do; could you explain?
I'm fairly certain file_descriptor_sink is not what you want...
Greetings,
