Subject: Check for EOF return before checking for errors
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=63432878fc84bc666bb74efaeee588fa6d03d5b2;hp=63432878fc84bc666bb74efaeee588fa6d03d5b2;p=libs%2Fnet.git

Check for EOF return before checking for errors

The check_sys_error function converts errors from non-blocking operations
which would block into a zero return, making them indistinguishable from
a zero return due to the other end closing the connection.
