network/multithreaded programming on FreeBSD

[Michael S]

Good day all,

I am not sure this is the correct list for my
question, I am still going to ask though. 
I am a 3rd year computer science student and in the
fall I am going to be taking courses in network and
system programming (with pthread). As a lot of
universities do, mine also teaches these courses on
Linux. I was wondering if there was a lot of
difference in socket and multi-threaded programming
between Linux and FreeBSD?

Thanks in advance,
Michael
