Subject: small issue in getifaddrs(3) man page
Date: Fri, 28 Feb 2020 07:33:54 -0800 [thread overview]
Message-ID: <CADFiD2+vbh-rhbj3G8z5F46R6cP1BSOVfpFiJju=EM00Q15-Ug@mail.gmail.com> (raw)
Hi,
The getifaddrs(3) man page has some sample code which includes a for
loop wich initializes and increments an in named "n" which is never
used. This is slightly confusing (but in no way wrong). The page
would be clearer if this variable declaration, initialization, and
increment were removed.
The two lines in question are:
int family, s, n;
...
for (ifa = ifaddr, n = 0; ifa != NULL; ifa = ifa->ifa_next, n++) {
Thanks.
