Now ive done it myself :P ner ner ne ner ner :) git-svn-id: http://svn.inspircd.org/repository/trunk/inspircd@8332 e03df62e-2008-0410-955e-edbf42e46eb7 --- src/socketengine_kqueue.cpp | 169 -------------------------------------------- 1 file changed, 169 deletions(-) delete mode 100644 src/socketengine_kqueue.cpp (limited to 'src/socketengine_kqueue.cpp') diff --git a/src/socketengine_kqueue.cpp b/src/socketengine_kqueue.cpp deleted file mode 100644 index 50f6242e2..000000000 --- a/src/socketengine_kqueue.cpp +++ /dev/null @@ -1,169 +0,0 @@ -/* +------------------------------------+ - * | Inspire Internet Relay Chat Daemon | - * +------------------------------------+ - * - * InspIRCd: (C) 2002-2007 InspIRCd Development Team - * See: http://www.inspircd.org/wiki/index.php/Credits - * - * This program is free but copyrighted software; see - * the file COPYING for details. - * - * --------------------------------------------------- - */ - -#include "inspircd.h" -#include "exitcodes.h" -#include -#include -#include -#include "socketengine_kqueue.h" - - -KQueueEngine::KQueueEngine(InspIRCd* Instance) : SocketEngine(Instance) -{ - this->RecoverFromFork(); -} - -void KQueueEngine::RecoverFromFork() -{ - /* - * The only bad thing about kqueue is that its fd cant survive a fork and is not inherited. - * BUM HATS. - * - */ - EngineHandle = kqueue(); - if (EngineHandle == -1) - { - ServerInstance->Log(SPARSE,"ERROR: Could not initialize socket engine.
