[olsr-dev] Re: Socket parser and HNA routes' update [QUESTIONS]

[Patrick McCarty]

Well now that makes sense,

I was struggling to understand how others had hooked into that,
although I hadn't really tackled it yet.

Perhaps all symbols are now in fact exported :)

This is both good and bad. Good because it sounds like the interface
is much more straight forward and has more hooks. Bad because I
haven't done much shared object linking and programming.

If you figure anything out, love to hear about it... I think it's
worthy of some quick documentation (if nothing else than for my own
posterity...)

Thanks,

Patrick
