From acc911ae724d42aaa2fecaa6f9b30651a91ad240 Mon Sep 17 00:00:00 2001 From: Robin Haberkorn Date: Sun, 2 Nov 2014 20:00:45 +0100 Subject: implemented EC command (execute operating system command) in spawn.cpp powerful command for filtering a SciTECO buffer through an external program. It will be described in the sciteco(7) man pages. The implementation uses an asynchronous background process with pipes but is platform independant thanks to glib's g_spawn functions, GIOChannels and event loops. There are however platform differences in how the operating system command is interpreted/parsed. --- src/spawn.h | 56 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 56 insertions(+) create mode 100644 src/spawn.h (limited to 'src/spawn.h') diff --git a/src/spawn.h b/src/spawn.h new file mode 100644 index 0000000..b6cb298 --- /dev/null +++ b/src/spawn.h @@ -0,0 +1,56 @@ +/* + * Copyright (C) 2012-2014 Robin Haberkorn + * + * 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 3 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.
