From 83e82dba47aced4a93f9e431b4d8bca94c2f8517 Mon Sep 17 00:00:00 2001 From: Linus Nordberg Date: Thu, 11 Nov 2010 10:30:35 +0100 Subject: Bringing up TLS connections working. NOTE: Clean up of resources not yet sane. Expect resource leakages. NOTE: Most failure cases are not handled properly. With the wind at your back and the sun shining, it might work. --- debug.c | 217 ---------------------------------------------------------------- 1 file changed, 217 deletions(-) delete mode 100644 debug.c (limited to 'debug.c') diff --git a/debug.c b/debug.c deleted file mode 100644 index 3bbcd0a..0000000 --- a/debug.c +++ /dev/null @@ -1,217 +0,0 @@ -/* - * Copyright (C) 2007 Stig Venaas - * - * Permission to use, copy, modify, and distribute this software for any - * purpose with or without fee is hereby granted, provided that the above - * copyright notice and this permission notice appear in all copies. - */ - -#ifndef SYS_SOLARIS9 -#include -#endif -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include "debug.h" -#include "util.h" - -static char *debug_ident = NULL;
