I noticed that the getifaddrs(3) library function doesn't behave as described in the manpage. The manpage says:
The ifa_data field references address family specific data. For AF_LINK addresses it contains a pointer to the struct if_data (as defined in include file <net/if.h>) which contains various interface attributes and statistics. This is correct and works. For all other address families, it contains a pointer to the struct ifa_data (as defined in include file <net/if.h>) which contains per‐address interface statistics. This is not what I'm seeing. First, I can't find a struct ifa_data definition, and second, the ifa_data field seems to be NULL for all address types other than AF_LINK. I'm thinking there are three possible explanations for this behaviour: - I need to set some non-default option to enable the ifa_data field for non-AF_LINK addresses. - There's a regression; the ifa_data field should contain data for non-AF_LINK addresses but no longer does. - The behaviour is correct, but the manpageis outdated. Please give me a bit more background information on this issue.
