Hi there
>From the getsockopt(2) manual page says getsockopt(2) returns -1 on
error and 0 on success. Also getpeereid(3) only lists those 2 values.
This diff makes the return value check in getpeereid explicit. I guess
this is how it is done elsewhere in the tree (there is a commit turning
a bunch of "... < 0" to "== -1" I think this falls under that category).
Best,
Martin
