Subject: [RFC PATCH 32/52] Y2038: add function __settimeofday_t64
Date: Thu, 07 Sep 2017 22:44:00 -0000	[thread overview]
Message-ID: <20170907224219.12483-33-albert.aribaud@3adev.fr> (raw)
In-Reply-To: <20170907224219.12483-32-albert.aribaud@3adev.fr>

Implementing a 64-bit settimeofday requires adding a new
file to build under time/ and we cannot name that new file
'settimeofday.c' or it will break the 32-bit settimeofday
symbol, so we call it 'settimeofday64.c'.
