From f714be125c9b85e184a482bc22e958b5cadfad3a Mon Sep 17 00:00:00 2001 From: Petar Paradzik <petar.paradzik@sartura.hr> Date: Mon, 3 Jul 2017 13:37:56 +0200 Subject: [PATCH] uloop: make SIGCHLD signal handling optional Some programs want to manage their own child life cycle without using SIGCHLD signal handler. In these cases, uloop is reaping children for them because they don't have SIGCHLD handler set. This patch makes it possible to disable reaping children through 'uloop_handle_sigchld' variable.
