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

[Leonard Ritter]

i have a function which i wish to wrap, which returns a float buffer and an
integer:

std::vector<float> get_recording_buffer(/* out */ size_t &write_ptr);

alternatively, the function could also just return a pointer to a float
array:

const float *get_recording_buffer(/* out */ size_t &size, /* out */ size_t
&write_ptr);

the signature doesn't matter as much as the intention here.

using boost.python, how can i export the method so its appropriate python
counterpart would be something like:

def get_recording_buffer():
    return (<float list or tuple>, <int>)

i skimmed through the tutorial, the faq and the wiki, but found nothing
related to these two issues.

thank you in advance :)
