Unix Socket Programming Question:

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.
