From 2ffe52a116ad05d060cbedda93c48cf5a4415ca3 Mon Sep 17 00:00:00 2001 From: Sean Bright Date: Thu, 7 Dec 2017 10:52:39 -0500 Subject: utils: Add convenience function for setting fd flags There are many places in the code base where we ignore the return value of fcntl() when getting/setting file descriptior flags. This patch introduces a convenience function that allows setting or clearing file descriptor flags and will also log an error on failure for later analysis.
