[libvirt] [PATCH 06/13] virsh: Split cmds to manage network from virsh.c

Commands to manage network are moved from virsh.c to virsh-network.c, with a few helpers for network command use. * virsh.c: Remove network commands and a few helpers. * virsh-network.c: New file, filled with network commands its helpers. --- tools/virsh-network.c | 688 +++++++++++++++++++++++++++++++++++++++++++++++++ tools/virsh.c | 678 +------------------------------------------------ 2 files changed, 690 insertions(+), 676 deletions(-) create mode 100644 tools/virsh-network.c diff --git a/tools/virsh-network.c b/tools/virsh-network.c new file mode 100644 index 0000000..459ccfe --- /dev/null +++ b/tools/virsh-network.c @@ -0,0 +1,688 @@ +/* + * virsh-network.c: Commands to manage network + * + * Copyright (C) 2005, 2007-2012 Red Hat, Inc + * + * This library is free software; you can redistribute it and/or + * modify it under the terms of the GNU Lesser General Public + * License as published by the Free Software Foundation; either + * version 2.1 of the License, or (at your option) any later version. + * + * This library 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.
