Creates a new #NMSettingConnection object with default values.
Whether or not the connection should be automatically connected by NetworkManager when the resources for the connection are available. %TRUE to automatically activate the connection, %FALSE to require manual intervention to activate the connection.
If greater than zero, delay success of IP addressing until either the timeout is reached, or an IP gateway replies to a ping.
A human readable unique identifier for the connection, like "Work Wi-Fi" or "T-Mobile 3G".
The name of the network interface this connection is bound to. If not set, then the connection can be attached to any interface of the appropriate type (subject to restrictions imposed by other settings).
For software devices this specifies the name of the created device.
For connection types where interface names cannot easily be made persistent (e.g. mobile broadband or USB Ethernet), this property should not be used. Setting this property restricts the interfaces a connection can be used with, and if interface names change or are reordered the connection may be applied to the wrong interface.
Interface name of the master device or UUID of the master connection.
The setting's name, which uniquely identifies the setting within the connection. Each setting type has a name unique to that type, for example "ppp" or "wireless" or "wired".
%FALSE if the connection can be modified using the provided settings service's D-Bus interface with the right privileges, or %TRUE if the connection is read-only and cannot be modified.
Setting name of the device type of this slave's master connection (eg, %NM_SETTING_BOND_SETTING_NAME), or %NULL if this connection is not a slave.
The time, in seconds since the Unix Epoch, that the connection was last successfully fully activated.
NetworkManager updates the connection timestamp periodically when the connection is active to ensure that an active connection has the latest timestamp. The property is only meant for reading (changes to this property will not be preserved).
Base type of the connection. For hardware-dependent connections, should contain the setting name of the hardware-type specific setting (ie, "802-3-ethernet" or "802-11-wireless" or "bluetooth", etc), and for non-hardware dependent connections like VPN or otherwise, should contain the setting name of that setting type (ie, "vpn" or "bridge", etc).
A universally unique identifier for the connection, for example generated with libuuid. It should be assigned when the connection is created, and never changed as long as the connection still applies to the same network. For example, it should not be changed when the #NMSettingConnection:id property or #NMSettingIP4Config changes, but might need to be re-created when the Wi-Fi SSID, mobile broadband network provider, or #NMSettingConnection:type property changes.
The UUID must be in the format "2815492f-7e56-435e-b2e9-246bd7cdc664" (ie, contains only hexadecimal characters and "-"). A suitable UUID may be generated by nm_utils_uuid_generate() or nm_utils_uuid_generate_from_string().
The trust level of a the connection. Free form case-insensitive string (for example "Home", "Work", "Public"). %NULL or unspecified zone means the connection will be placed in the default zone as defined by the firewall.
Adds a permission to the connection's permission list. At this time, only
the "user" permission type is supported, and pitem must be a username. See
#NMSettingConnection:permissions: for more details.

Creates a binding between source_property on source and target_property
on target.
Whenever the source_property is changed the target_property is
updated using the same value. For instance:
g_object_bind_property (action, "active", widget, "sensitive", 0);
Will result in the "sensitive" property of the widget #GObject instance to be updated with the same value of the "active" property of the action #GObject instance.
If flags contains %G_BINDING_BIDIRECTIONAL then the binding will be mutual:
if target_property on target changes then the source_property on source
will be updated as well.
The binding will automatically be removed when either the source or the
target instances are finalized. To remove the binding without affecting the
source and the target you can just call g_object_unref() on the returned
#GBinding instance.
Removing the binding by calling g_object_unref() on it must only be done if
the binding, source and target are only used from a single thread and it
is clear that both source and target outlive the binding. Especially it
is not safe to rely on this if the binding, source or target can be
finalized from different threads. Keep another reference to the binding and
use g_binding_unbind() instead to be on the safe side.
A #GObject can have multiple bindings.

This function is intended for #GObject implementations to re-enforce a [floating][floating-ref] object reference. Doing this is seldom required: all #GInitiallyUnowneds are created with a floating reference which usually just needs to be sunken by calling g_object_ref_sink().
Increases the freeze count on object. If the freeze count is
non-zero, the emission of "notify" signals on object is
stopped. The signals are queued until the freeze count is decreased
to zero. Duplicate notifications are squashed so that at most one
#GObject::notify signal is emitted for each property modified while the
object is frozen.
This is necessary for accessors that modify multiple properties to prevent premature notification while the object is still being modified.

Gets a property of an object.
The value can be:
In general, a copy is made of the property contents and the caller is responsible for freeing the memory by calling g_value_unset().
Note that g_object_get_property() is really intended for language bindings, g_object_get() is much more convenient for C programming.

Checks whether object has a [floating][floating-ref] reference.
Returns an array of property names for each secret which may be required 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.
Emits a "notify" signal for the property property_name on object.
When possible, eg. when signaling a property change from within the class that registered the property, you should use g_object_notify_by_pspec() instead.
Note that emission of the notify signal may be blocked with g_object_freeze_notify(). In this case, the signal emissions are queued and will be emitted (in reverse order) when g_object_thaw_notify() is called.
the name of a property installed on the class of object.
Emits a "notify" signal for the property specified by pspec on object.
This function omits the property name lookup, hence it is faster than g_object_notify().
One way to avoid using g_object_notify() from within the class that registered the properties, and using g_object_notify_by_pspec() instead, is to store the GParamSpec used with g_object_class_install_property() inside a static array, e.g.:
enum
{
PROP_0,
PROP_FOO,
PROP_LAST
};
static GParamSpec *properties[PROP_LAST];
static void
my_object_class_init (MyObjectClass *klass)
{
properties[PROP_FOO] = g_param_spec_int ("foo", "Foo", "The foo",
0, 100,
50,
G_PARAM_READWRITE);
g_object_class_install_property (gobject_class,
PROP_FOO,
properties[PROP_FOO]);
}
and then notify a change on the "foo" property with:
g_object_notify_by_pspec (self, properties[PROP_FOO]);

Checks whether the given username is allowed to view/access this connection.

Increase the reference count of object, and possibly remove the
[floating][floating-ref] reference, if object has a floating reference.
In other words, if the object is floating, then this call "assumes ownership" of the floating reference, converting it to a normal reference by clearing the floating flag while leaving the reference count unchanged. If the object is not floating, then this call adds a new normal reference increasing the reference count by one.
Since GLib 2.56, the type of object will be propagated to the return type
under the same conditions as for g_object_ref().

Releases all references to other objects. This can be used to break reference cycles.
This function should only be called from object system implementations.
Each object carries around a table of associations from strings to pointers. This function lets you set an association.
If the object already had an association with that name, the old association will be destroyed.
Internally, the key is converted to a #GQuark using g_quark_from_string().
This means a copy of key is kept permanently (even after object has been
finalized) — so it is recommended to only use a small, bounded set of values
for key in your program, to avoid the #GQuark storage growing unbounded.

This function gets back user data pointers stored via
g_object_set_qdata() and removes the data from object
without invoking its destroy() function (if any was
set).
Usually, calling this function is only required to update
user data pointers with a destroy notifier, for example:
void
object_add_to_user_list (GObject *object,
const gchar *new_string)
{
// the quark, naming the object data
GQuark quark_string_list = g_quark_from_static_string ("my-string-list");
// retrieve the old string list
GList *list = g_object_steal_qdata (object, quark_string_list);
// prepend new string
list = g_list_prepend (list, g_strdup (new_string));
// this changed 'list', so we need to set it again
g_object_set_qdata_full (object, quark_string_list, list, free_string_list);
}
static void
free_string_list (gpointer data)
{
GList *node, *list = data;
for (node = list; node; node = node->next)
g_free (node->data);
g_list_free (list);
}
Using g_object_get_qdata() in the above example, instead of g_object_steal_qdata() would have left the destroy function set, and thus the partial string list would have been freed upon g_object_set_qdata_full().
A #GQuark, naming the user data pointer
Reverts the effect of a previous call to
g_object_freeze_notify(). The freeze count is decreased on object
and when it reaches zero, queued "notify" signals are emitted.
Duplicate notifications for each property are squashed so that at most one #GObject::notify signal is emitted for each property, in the reverse order in which they have been queued.
It is an error to call this function when the freeze count is zero.
Converts the #NMSetting into a #GHashTable mapping each setting property name to a GValue describing that property, suitable for marshalling over D-Bus or serializing. The mapping is string to GValue.
hash flags, e.g. %NM_SETTING_HASH_FLAG_ALL
Convert the setting into a string. For debugging purposes ONLY, should NOT be used for serialization of the setting, or machine-parsed in any way. The output format is not guaranteed to be stable and may change at any time.
Decreases the reference count of object. When its reference count
drops to 0, the object is finalized (i.e. its memory is freed).
If the pointer to the #GObject may be reused in future (for example, if it is an instance variable of another object), it is recommended to clear the pointer to %NULL rather than retain a dangling pointer to a potentially invalid #GObject instance. Use g_clear_object() for this.
Update the setting's secrets, given a hash table of secrets intended for that setting (deserialized from D-Bus for example).
a #GHashTable mapping string to #GValue of setting property names and secrets
Validates the setting. Each setting's properties have allowed values, and
some are dependent on other values (hence the need for all_settings). The
returned #GError contains information about which property of the setting
failed validation, and in what way that property failed validation.
a #GSList of all settings in the connection from which setting came
This function essentially limits the life time of the closure to
the life time of the object. That is, when the object is finalized,
the closure is invalidated by calling g_closure_invalidate() on
it, in order to prevent invocations of the closure with a finalized
(nonexisting) object. Also, g_object_ref() and g_object_unref() are
added as marshal guards to the closure, to ensure that an extra
reference count is held on object during invocation of the
closure. Usually, this function will be called on closures that
use this object as closure data.

name of a property to look up.
Add a property to an interface; this is only useful for interfaces that are added to GObject-derived types. Adding a property to an interface forces all objects classes with that interface to have a compatible property. The compatible property could be a newly created #GParamSpec, but normally g_object_class_override_property() will be used so that the object class only needs to provide an implementation and inherits the property description, default value, bounds, and so forth from the interface property.
This function is meant to be called from the interface's default
vtable initialization function (the class_init member of
#GTypeInfo.) It must not be called after after class_init has
been called for any object types implementing this interface.
If pspec is a floating reference, it will be consumed.

Creates a new #NMSettingConnection object with default values.
Creates a new #NMSetting object and populates that object with the properties contained in the hash table, using each hash key as the property to set, and each hash value as the value to set that property to.
