Musings on public API

Hey Harald, Andreas, I just tried to come up with a patch to prefix the timer functions with bsc_ and started to think about public API. The thing is we only need to properly prefix symbols we intend to export. I don't think we will export timers. So the questions I think of are: what are we going to export? how are we going to export it? On the what question it mostly depends on Andreas and what he needs for his application, from what I understand that is the MNCC stuff that will come as one of his patches. For the other question of how we are going to export it we have at least two approaches, symbol filter and visibility attributes of the gcc. I prefer the later and have cooked up an example patch... comments welcome z. PS: I'm sorry to use libtool... the GNU documentation tries to hide other ways PPS: With the 2nd patch in place I don't think we need to rename the timer symbols (we still can as a matter of cleaning it up) PPS: With the 2nd patch we have everything in place for installable API...
