[LTP] [PATCH 12/12] posix/interface/conformance: Fix/supress all unused-result warnings
Joerg Vehlow
lkml@jv-coder.de
Fri Nov 19 08:46:02 CET 2021
From: Joerg Vehlow <joerg.vehlow@aox-tech.de>
The warnings for writes in signalhandlers can only be suppressed,
there is no good way to handle an error there. In all other locations
a failing function is printed and PTS_UNRESOLVED returned.
Signed-off-by: Joerg Vehlow <joerg.vehlow@aox-tech.de>
