What's with the second parameter in bind()?
The man page shows it as "struct sockaddr *my_addr". The sockaddr
struct though is just a place holder for the structure it really
wants. You have to pass different structures depending on what kind
of socket you have. For an AF_INET socket, you need the sockaddr_in
structure. It has three fields of interest:
sin_family
Set this to AF_INET.
sin_port
The network byte-ordered 16 bit port number
sin_addr
The host's ip number.
This is a struct in_addr,
which contains only one field,
s_addr which is a u_long.
