I want to call this function:
No, you don't :-)
Boolean SCNetworkCheckReachabilityByAddress (

A struct sockaddr is:
struct sockaddr {
u_char sa_len; /* total length */
u_char sa_family; /* address family */
char sa_data[14]; /* actually longer; address value */
};
I don't know how the struct should be filled in in order to call the
above function. Can anyone point me to some example code that fills that
struct in for a normal web address e.g. amazon.com?

You actually want to call SCNetworkCheckReachabilityByName.
