[libvirt] [libvirt-glib 4/4] Implement gvir_config_domain_get_devices

There are some devices which we are not able to parse yet, in these cases a runtime warning is printed to tell what's going on. --- libvirt-gconfig/Makefile.am | 1 + .../libvirt-gconfig-domain-device-private.h | 45 ++++++++++++++ libvirt-gconfig/libvirt-gconfig-domain-device.c | 62 ++++++++++++++++++++ libvirt-gconfig/libvirt-gconfig-domain-disk.c | 29 +++++++++- libvirt-gconfig/libvirt-gconfig-domain-graphics.c | 33 ++++++++++ libvirt-gconfig/libvirt-gconfig-domain-interface.c | 38 ++++++++++++ libvirt-gconfig/libvirt-gconfig-domain.c | 41 +++++++++++++ libvirt-gconfig/libvirt-gconfig-domain.h | 1 + libvirt-gconfig/libvirt-gconfig-private.h | 1 + libvirt-gconfig/libvirt-gconfig.sym | 1 + 10 files changed, 251 insertions(+), 1 deletions(-) create mode 100644 libvirt-gconfig/libvirt-gconfig-domain-device-private.h diff --git a/libvirt-gconfig/Makefile.am b/libvirt-gconfig/Makefile.am index d9eb25a..34c5cc5 100644 --- a/libvirt-gconfig/Makefile.am +++ b/libvirt-gconfig/Makefile.am @@ -52,6 +52,7 @@ GCONFIG_HEADER_FILES = \ libvirt-gconfig-storage-vol-target.h noinst_HEADERS = \ libvirt-gconfig-private.h \ + libvirt-gconfig-domain-device-private.h \ libvirt-gconfig-helpers-private.h \ libvirt-gconfig-object-private.h \ libvirt-gconfig-xml-doc.h diff --git a/libvirt-gconfig/libvirt-gconfig-domain-device-private.h b/libvirt-gconfig/libvirt-gconfig-domain-device-private.h new file mode 100644 index 0000000..7ba7bc6 --- /dev/null +++ b/libvirt-gconfig/libvirt-gconfig-domain-device-private.h @@ -0,0 +1,45 @@ +/* + * libvirt-gconfig-domain-device-private.h: libvirt domain device configuration + * + * Copyright (C) 2011 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.
