[C++-sig] returning vector arrays and multiple values

[Leonard Ritter]

thanks for your help, the solution i used was this one:

#include <boost/python.hpp>
#include <boost/python/suite/indexing/vector_indexing_suite.hpp>
using namespace boost::python;

tuple py_audio_get_recording_buffer() {
    int write_ptr = 0;
    std::vector<float> buffer = audio_get_recording_buffer(write_ptr);
    return make_tuple(buffer, write_ptr);
}

BOOST_PYTHON_MODULE(nucleus) {
    class_< std::vector<float> >("vector_float")
        .def(vector_indexing_suite< std::vector<float> >());

    def("get_recording_buffer", py_audio_get_recording_buffer);
}
