I want to call this function:
Boolean SCNetworkCheckReachabilityByAddress (
const struct sockaddr *address,
int addrlen,
SCNetworkConnectionFlags *flags );
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?
Why not use SCNetworkReachabilityCreateWithName?
Also in an email on the Cocoa developer list you stated that you
wanted to target 10.2 and later. The above API is only available on
10.3 and later (not that you couldn't use it on 10.3 and later and
use something when running on 10.2).
