AUTOSAR SOME/IP container: C++11/STL parsing library

KS implementation details

Minimal Kaitai Struct required: 0.9

This page hosts a formal specification of AUTOSAR SOME/IP container using Kaitai Struct. This specification can be automatically translated into a variety of programming languages to get a parsing library.


Runtime library

All parsing code for C++11/STL generated by Kaitai Struct depends on the C++/STL runtime library. You have to install it before you can parse data.

For C++, the easiest way is to clone the runtime library sources and build them along with your project.


Using Kaitai Struct in C++/STL usually consists of 3 steps.

  1. We need to create an STL input stream (std::istream). One can open local file for that, or use existing std::string or char* buffer.
    #include <fstream>
    std::ifstream is("path/to/local/file.bin", std::ifstream::binary);
    #include <sstream>
    std::istringstream is(str);
    #include <sstream>
    const char buf[] = { ... };
    std::string str(buf, sizeof buf);
    std::istringstream is(str);
  2. We need to wrap our input stream into Kaitai stream:
    #include "kaitai/kaitaistream.h"
    kaitai::kstream ks(&is);
  3. And finally, we can invoke the parsing:
    some_ip_container_t data(&ks);

After that, one can get various attributes from the structure by invoking getter methods like:

data.some_ip_packages() // => get some ip packages
