You're filling in addr, but then binding to sin,
which is uninitialized and probably contains zero
or else stack garbage, either way not what you want.
Aside: you don't need to cast (char*)&addr for memset
since C switched to void* in 1989. However, you do need
(sockaddr*)&a_sockaddr_in (or other sockaddr_x types),
since those are not special the way void is.
