From 6ff9c31abc14f207265ab214370982ecb3bfe428 Mon Sep 17 00:00:00 2001 From: Bernhard Reutner-Fischer Date: Wed, 25 Mar 2015 23:59:45 +0100 Subject: utmp: favour POSIX utmpx over SVID utmp Note: _PATH_UTMPX == _PATH_UTMP and the utmp struct is identical to the utmpx struct so this only changes the external API entrypoints and NOT the underlying data source. This saves about 500b (~1300b from previously ~1950) while at it.
