Synopsis: problem with SIOCGIFCONF

State-Changed-From-To: open-closed
State-Changed-By: fenner
State-Changed-When: Thu Jul 9 16:55:04 PDT 1998
State-Changed-Why: 
The SIOCGIFCONF interface changed in 4.3-Reno (when sa_len was introduced).
The return value includes a list of struct ifreqs, but you have to check
the size of the struct sockaddr inside the struct ifreq to see where the
next ifreq starts.  See, for example, the code on page 436 of _UNIX
Network Programming, Volume 1_, second edition.
