From: Scott Lamb Date: Tue, 27 Feb 2007 01:26:11 +0000 (+0000) Subject: Rename "event_t" to "tevent_t", along with associated functions. X-Git-Tag: import-tinc-1.1~674 X-Git-Url: https://git.meshlink.io/?a=commitdiff_plain;h=6362b12df725044f3404faceff113e469d8ac860;p=meshlink Rename "event_t" to "tevent_t", along with associated functions. This relieves some confusion and problems during the libevent transition. In particular, "event_add" was defined by both. (The 't' stands for 'timeout', 'tinc', 'temporary', or some such.) --- diff --git a/src/Makefile.am b/src/Makefile.am index 10f07af5..c9c1ac90 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -5,7 +5,7 @@ sbin_PROGRAMS = tincd EXTRA_DIST = linux/device.c bsd/device.c solaris/device.c cygwin/device.c mingw/device.c mingw/common.h raw_socket/device.c uml_socket/device.c -tincd_SOURCES = conf.c connection.c edge.c event.c graph.c logger.c meta.c net.c net_packet.c net_setup.c \ +tincd_SOURCES = conf.c connection.c edge.c tevent.c graph.c logger.c meta.c net.c net_packet.c net_setup.c \ net_socket.c netutl.c node.c process.c protocol.c protocol_auth.c protocol_edge.c protocol_misc.c \ protocol_key.c protocol_subnet.c route.c subnet.c tincd.c @@ -15,7 +15,7 @@ DEFAULT_INCLUDES = INCLUDES = @INCLUDES@ -I$(top_builddir) -I$(top_srcdir)/lib -noinst_HEADERS = conf.h connection.h device.h edge.h event.h graph.h logger.h meta.h net.h netutl.h node.h process.h \ +noinst_HEADERS = conf.h connection.h device.h edge.h tevent.h graph.h logger.h meta.h net.h netutl.h node.h process.h \ protocol.h route.h subnet.h LIBS = @LIBS@ @LIBINTL@ diff --git a/src/event.c b/src/event.c deleted file mode 100644 index c791205f..00000000 --- a/src/event.c +++ /dev/null @@ -1,127 +0,0 @@ -/* - event.c -- event queue - Copyright (C) 2002-2006 Guus Sliepen , - 2002-2005 Ivo Timmermans - - This program is free software; you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation; either version 2 of the License, or - (at your option) any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
