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:

1.sin_family

Set this to AF_INET.

2.sin_port

The network byte-ordered 16 BIT port number

3.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.
