Author: ngie Date: Tue Jul 18 08:35:22 2017 New Revision: 321121 URL: https://svnweb.freebsd.org/changeset/base/321121 Log: MFC r318257,r318278: r318257: style(9): sort headers r318278: Mark errf _Noreturn, and mark errf and warn __printflike The _Noreturn attribute was added to placate Coverity and other static analysis tools. The __printflike attribute was added to catch issues with the calls related to printf(3) abuse. - Modify the code to facilitate the __printflike attribute addition. - Convert errf calls in to_mb(..) and to_mb_string(..) to warn(..) so the calls will return instead of exiting, as the code suggests it should.
