An NMConnection describes all the settings and configuration values that are necessary to configure network devices for operation on a specific network. Connections are the fundamental operating object for NetworkManager; no device is connected without a NMConnection, or disconnected without having been connected with a NMConnection.
Each NMConnection contains a list of NMSetting objects usually referenced
by name (using nm_connection_get_setting_by_name()) or by type (with
nm_connection_get_setting()). The settings describe the actual parameters
with which the network devices are configured, including device-specific
parameters (MTU, SSID, APN, channel, rate, etc) and IP-level parameters
(addresses, routes, addressing methods, etc).
void nm_connection_add_setting (NMConnection *connection,NMSetting *setting);
Adds a NMSetting to the connection, replacing any previous NMSetting of the same name which has previously been added to the NMConnection. The connection takes ownership of the NMSetting object and does not increase the setting object's reference count.
void nm_connection_remove_setting (NMConnection *connection,GType setting_type);
Removes the NMSetting with the given GType from the NMConnection. This operation dereferences the NMSetting object.
NMSetting * nm_connection_get_setting (NMConnection *connection,GType setting_type);
Gets the NMSetting with the given GType, if one has been previously added to the NMConnection.
the NMSetting, or NULL if no setting of that type was previously
added to the NMConnection.

NMSetting * nm_connection_get_setting_by_name (NMConnection *connection,const char *name);
Gets the NMSetting with the given name, if one has been previously added the NMConnection.
the NMSetting, or NULL if no setting with that name was previously
added to the NMConnection.
[transfer none]
GVariant * nm_connection_to_dbus (NMConnection *connection,NMConnectionSerializationFlags flags);
Converts the NMConnection into a GVariant of type
NM_VARIANT_TYPE_CONNECTION describing the connection, suitable for
marshalling over D-Bus or otherwise serializing.
a new floating GVariant describing the connection, its settings, and each setting's properties.
[transfer none]
gboolean nm_connection_replace_settings (NMConnection *connection,GVariant *new_settings,GError **error);
Replaces connection
's settings with new_settings
(which must be
syntactically valid, and describe a known type of connection, but does not
need to result in a connection that passes nm_connection_verify()).
void nm_connection_replace_settings_from_connection (NMConnection *connection,NMConnection *new_connection);
Deep-copies the settings of new_connection
and replaces the settings of connection
with the copied settings.
void
nm_connection_clear_settings (NMConnection *connection);
Deletes all of connection
's settings.
gboolean nm_connection_compare (NMConnection *a,NMConnection *b,NMSettingCompareFlags flags);
Compares two NMConnection objects for similarity, with comparison behavior
modified by a set of flags. See nm_setting_compare() for a description of
each flag's behavior.

compare flags, e.g. |
gboolean nm_connection_diff (NMConnection *a,NMConnection *b,NMSettingCompareFlags flags,GHashTable **out_settings);
Compares two NMConnection objects for similarity, with comparison behavior
modified by a set of flags. See nm_setting_compare() for a description of
each flag's behavior. If the connections differ, settings and keys within
each setting that differ are added to the returned out_settings
hash table.
No values are returned, only key names.

[element-type utf8 GLib.HashTable] |
gboolean nm_connection_verify (NMConnection *connection,GError **error);
Validates the connection and all its settings. Each setting's properties have allowed values, and some values are dependent on other values. For example, if a Wi-Fi connection is security enabled, the NMSettingWireless setting object's 'security' property must contain the setting name of the NMSettingWirelessSecurity object, which must also be present in the connection for the connection to be valid. As another example, the NMSettingWired object's 'mac-address' property must be a validly formatted MAC address. The returned GError contains information about which setting and which property failed validation, and how it failed validation.
gboolean nm_connection_verify_secrets (NMConnection *connection,GError **error);
Verifies the secrets in the connection.
Since: 1.2
gboolean nm_connection_normalize (NMConnection *connection,GHashTable *parameters,gboolean *modified,GError **error);
Does some basic normalization and fixup of well known inconsistencies
and deprecated fields. If the connection was modified in any way,
the output parameter modified
is set TRUE.
Finally the connection will be verified and TRUE returns if the connection
is valid. As this function only performs some specific normalization steps
it cannot repair all connections. If the connection has errors that
cannot be normalized, the connection will not be modified.

const char * nm_connection_need_secrets (NMConnection *connection,GPtrArray **hints);
Returns the name of the first setting object in the connection which would need secrets to make a successful connection. The returned hints are only intended as a guide to what secrets may be required, because in some circumstances, there is no way to conclusively determine exactly which secrets are needed.

intended for that setting (deserialized from D-Bus for example). Will also
extract the given setting's secrets hash if given a connection dictionary.

gboolean nm_connection_is_type (NMConnection *connection,const char *type);
