[Icecast] research question

[Gabrielle Anderson]

Heya,

I'm a PhD student at the University of Southampton. I'm researching the how
multi-threaded software uses shared resources such as shared state and
message passing over networks etc, and how those uses change across software
versions. I am attempting to read through the source code of Icecast but
don't have a great understanding of multi-threaded C so if anyone could give
me pointers or a general description about how the shared
variables/condition variables are used and for what conceptual purpose I
would be much obliged.

Thanks,
Gabrielle

PS, I wasn't sure whether to post this on the developers' list or not so
thought it was safer to post here first.
