Hi,
While I had some questions concerning accessing objects in Python, that
were previously created in C++ now I'd like to know whether it's
possible to get access to the raw memory from Python layer.
Let's suppose I have the char* ptr pointer that points to the memory
chunk with IPv4 packet. I would like to be able to read (and preferably
write) data from Python layer (not via wrapped object that contains
char* ptr and has some methods to write/read data), but without making
any memory copies.
I can use struct (even define format dynamically) in Python, but I don't
know how do I pass the proper pointer from C++. If I use
boost::python::object I had problems that script didn't know char type.
I can use boost::python::str, return it and use in Python but I suppose
it does copy data into str object, right?
If not Boost, maybe basic Python C API would work?
BTW. Suppose I had char* txt = "some string";
How do i create boost::python::object() that would containt the whole
string? Passing *txt or txt into boost::python::object(*txt) didn't work.
