### nm_client_new ()

    NMClient *
    nm_client_new (GCancellable *cancellable,
                   GError **error);

Creates a new NMClient synchronously.

Note that this will block until a NMClient instance is fully initialized. This does nothing beside calling `g_initable_new()`. You are free to call `g_initable_new()` or `g_object_new()`/`g_initable_init()` directly for more control, to set GObject properties or get access to the NMClient instance while it is still initializing.

Using the synchronous initialization creates an NMClient instance that uses an internal GMainContext. This context is invisible to the user. This introduces an additional overhead that is payed not only during object initialization, but for the entire lifetime of this object. Also, due to this internal GMainContext, the events are no longer in sync with other messages from GDBusConnection (but all events of the NMClient will themselves still be ordered). For a serious program, you should therefore avoid these problems by using `g_async_initable_init_async()` or `nm_client_new_async()` instead. The sync initialization is still useful for simple scripts or interactive testing for example via pygobject.

Creating an NMClient instance can only fail for two reasons. First, if you didn't provide a `NM_CLIENT_DBUS_CONNECTION` and the call to `g_bus_get()` fails. You can avoid that by using `g_initable_new()` directly and set a D-Bus connection. Second, if you cancelled the creation. If you do that, then note that after the failure there might still be idle actions pending which keep `nm_client_get_main_context()` alive. That means, in that case you must continue iterating the context to avoid leaks. See `nm_client_get_context_busy_watcher()`.

Creating an NMClient instance when NetworkManager is not running does not cause a failure.

#### Parameters

cancellable | a GCancellable, or `NULL` |
error | location for a GError, or `NULL` |

#### Returns

a new NMClient or NULL on an error

### nm_client_new_async ()

    void
    nm_client_new_async (GCancellable *cancellable,
                         GAsyncReadyCallback callback,
                         gpointer user_data);

Creates a new NMClient asynchronously. `callback` will be called when it is done. Use `nm_client_new_finish()` to get the result.

This does nothing beside calling `g_async_initable_new_async()`. You are free to call `g_async_initable_new_async()` or `g_object_new()`/`g_async_initable_init_async()` directly for more control, to set GObject properties or get access to the NMClient instance while it is still initializing.

#### Parameters

cancellable | a GCancellable, or `NULL` |
callback | callback to call when the client is created |
user_data | data for `callback` |

### nm_client_new_finish ()

    NMClient *
    nm_client_new_finish (GAsyncResult *result,
                          GError **error);

Gets the result of an `nm_client_new_async()` call.

#### Parameters

result | a GAsyncResult |
error | location for a GError, or `NULL` |

#### Returns

a new NMClient, or `NULL` on error

### nm_client_get_instance_flags ()

    NMClientInstanceFlags
    nm_client_get_instance_flags (NMClient *self);

#### Returns

the NMClientInstanceFlags flags.

Since: 1.24

### nm_client_get_dbus_connection ()

    GDBusConnection *
    nm_client_get_dbus_connection (NMClient *client);

Gets the `GDBusConnection` of the instance. This can be either passed when constructing the instance (as "dbus-connection" property), or it will be automatically initialized during async/sync init.

#### Parameters

client | a NMClient |

#### Returns

the D-Bus connection of the client, or `NULL` if none is set.

[transfer none]

Since: 1.22

### nm_client_get_main_context ()

    GMainContext *
    nm_client_get_main_context (NMClient *self);

The NMClient instance is permanently associated with the current thread default GMainContext, referenced the time when the instance was created. To receive events, the user must iterate this context and can use it to synchronize access to the client.

Note that even after NMClient instance got destroyed, there might still be pending sources registered in the context. That means, to fully clean up, the user must continue iterating the context as long as the `nm_client_get_context_busy_watcher()` object is alive.

#### Parameters

self | the NMClient instance |

#### Returns

the GMainContext of the client.

[transfer none]

Since: 1.22

### nm_client_get_context_busy_watcher ()

    GObject *
    nm_client_get_context_busy_watcher (NMClient *self);

#### Parameters

self | the NMClient instance. |

#### Returns

a GObject that stays alive as long as there are pending D-Bus operations.

NMClient will schedule asynchronous D-Bus requests which will complete on the GMainContext associated with the instance. When destroying the NMClient instance, those requests are cancelled right away, however their pending requests are still outstanding and queued in the GMainContext. These outstanding callbacks keep the GMainContext alive. In order to fully release all resources, the user must keep iterating the main context until all these callbacks are handled. Of course, at this point no more actual callbacks will be invoked for the user, those are all cancelled internally.

This just leaves one problem: how long does the user need to keep the GMainContext running to ensure everything is cleaned up? The answer is this GObject. Subscribe a weak reference to the returned object and keep iterating the main context until the object got unreferenced.

Note that after the NMClient instance gets destroyed, all outstanding operations will be cancelled right away. That means, the user needs to iterate the GMainContext a bit longer, but it is guaranteed that the cleanup happens soon after.

The way of using the context-busy-watch, is by registering a weak pointer to see when it gets destroyed. That means, user code should not take additional references on this object to not keep it alive longer.

If you plan to exit the program after releasing the NMClient instance you may not need to worry about these "leaks". Also, if you anyway plan to continue iterating the GMainContext afterwards, then you don't need to care when exactly NMClient is gone completely.

                                         gpointer user_data);

Asynchronously starts a connection to a particular network using the configuration settings from `connection` and the network device `device` . Certain connection types also take a "specific object" which is the object path of a connection- specific object, like an NMAccessPoint for Wi-Fi connections, or an NMWimaxNsp for WiMAX connections, to which you wish to connect. If the specific object is not given, NetworkManager can, in some cases, automatically determine which network to connect to given the settings in `connection` .

If `connection` is not given for a device-based activation, NetworkManager picks the best available connection for the device and activates it.

Note that the callback is invoked when NetworkManager has started activating the new connection, not when it finishes. You can use the returned NMActiveConnection object (in particular, “state”) to track the activation to its completion.

#### Parameters

client | a NMClient |
connection | an NMConnection. | [allow-none]
device | the NMDevice. | [allow-none]
specific_object | the object path of a connection-type-specific object this activation should use. This parameter is currently ignored for wired and mobile broadband connections, and the value of `NULL` should be used (ie, no specific object). For Wi-Fi or WiMAX connections, pass the object path of a NMAccessPoint or NMWimaxNsp owned by `device` , which you can get using `nm_object_get_path()`, and which will be used to complete the details of the newly added connection. | [allow-none]
cancellable | a GCancellable, or `NULL` |
callback | callback to be called when the activation has started |
user_data | caller-specific data passed to `callback` |

### nm_client_activate_connection_finish ()

partial | an NMConnection to add; the connection may be partially filled (or even `NULL`) and will be completed by NetworkManager using the given `device` and `specific_object` before being added. | [allow-none]
device | the NMDevice |
specific_object | the object path of a connection-type-specific object this activation should use. This parameter is currently ignored for wired and mobile broadband connections, and the value of `NULL` should be used (ie, no specific object). For Wi-Fi or WiMAX connections, pass the object path of a NMAccessPoint or NMWimaxNsp owned by `device` , which you can get using `nm_object_get_path()`, and which will be used to complete the details of the newly added connection.

                                    gpointer user_data);

Adds a new connection using the given details (if any) as a template, automatically filling in missing settings with the capabilities of the given device and specific object. The new connection is then asynchronously activated as with `nm_client_activate_connection_async()`. Cannot be used for VPN connections at this time.

Note that the callback is invoked when NetworkManager has started activating the new connection, not when it finishes. You can used the returned NMActiveConnection object (in particular, “state”) to track the activation to its completion.

This is identical to `nm_client_add_and_activate_connection_async()` but takes a further `options` parameter. Currently, the following options are supported by the daemon:

- "persist": A string describing how the connection should be stored. The default is "disk", but it can be modified to "memory" (until the daemon quits) or "volatile" (will be deleted on disconnect).

- "bind-activation": Bind the connection lifetime to something. The default is "none", meaning an explicit disconnect is needed. The value "dbus-client" means the connection will automatically be deactivated when the calling D-Bus client disappears from the system bus.

#### Parameters

client | a NMClient |
partial | an NMConnection to add; the connection may be partially filled (or even `NULL`) and will be completed by NetworkManager using the given `device` and `specific_object` before being added. | [allow-none]
device | the NMDevice |
specific_object | the object path of a connection-type-specific object this activation should use. This parameter is currently ignored for wired and mobile broadband connections, and the value of `NULL` should be used (i.e., no specific object). For Wi-Fi or WiMAX connections, pass the object path of a NMAccessPoint or NMWimaxNsp owned by `device` , which you can get using `nm_object_get_path()`, and which will be used to complete the details of the newly added connection. | [allow-none]
options | a GVariant containing a dictionary with options, or `NULL` |
cancellable | a GCancellable, or `NULL` |
callback | callback to be called when the activation has started |
user_data | caller-specific data passed to `callback` |

### nm_client_add_connection_async ()

    void
    nm_client_add_connection_async (NMClient *client,
                                    NMConnection *connection,
                                    gboolean save_to_disk,
                                    GCancellable *cancellable,
                                    GAsyncReadyCallback callback,
                                    gpointer user_data);

Requests that the remote settings service add the given settings to a new connection. If `save_to_disk` is `TRUE`, the connection is immediately written to disk; otherwise it is initially only stored in memory, but may be saved later by calling the connection's `nm_remote_connection_commit_changes()` method.

`connection` is untouched by this function and only serves as a template of the settings to add. The NMRemoteConnection object that represents what NetworkManager actually added is returned to `callback` when the addition operation is complete.

Note that the NMRemoteConnection returned in `callback` may not contain identical settings to `connection` as NetworkManager may perform automatic completion and/or normalization of connection properties.

#### Parameters

client | the `NMClient` |
connection | the connection to add. Note that this object's settings will be added, not the object itself |
save_to_disk | whether to immediately save the connection to disk |
cancellable | a GCancellable, or `NULL` |
callback | callback to be called when the add operation completes. | [scope async]
user_data | caller-specific data passed to `callback` . | [closure]

### nm_client_add_connection_finish ()

                                     GError **error);

Gets the result of a call to `nm_client_add_connection_async()`.

#### Parameters

client | an NMClient |
result | the result passed to the GAsyncReadyCallback |
error | location for a GError, or `NULL` |

#### Returns

the new NMRemoteConnection on success, `NULL` on failure, in which case `error` will be set.

                               gpointer user_data);

Call `AddConnection2()` D-Bus API asynchronously.

#### Parameters

client | the `NMClient` |
settings | the "a{sa{sv}}" GVariant with the content of the setting. |
flags | the `NMSettingsAddConnection2Flags` argument. |
args | the "a{sv}" GVariant with extra argument or `NULL` for no extra arguments. | [allow-none]
ignore_out_result | this function wraps `AddConnection2()`, which has an additional result "a{sv}" output parameter. By setting this to `TRUE`, you signal that you are not interested in that output parameter. This allows the function to fall back to `AddConnection()` and `AddConnectionUnsaved()`, which is interesting if you run against an older server version that does not yet provide `AddConnection2()`. By setting this to `FALSE`, the function under the hood always calls `AddConnection2()`. |
cancellable | a GCancellable, or `NULL` |
callback | callback to be called when the add operation completes. | [scope async]
user_data | caller-specific data passed to `callback` . | [closure]

#### Parameters

client | the NMClient |

### nm_client_load_connections ()

    gboolean
    nm_client_load_connections (NMClient *client,

                                char ***failures,
                                GCancellable *cancellable,
                                GError **error);

`nm_client_load_connections` has been deprecated since version 1.22 and should not be used in newly-written code.

Use `nm_client_load_connections_async()` or GDBusConnection.

Requests that the remote settings service load or reload the given files, adding or updating the connections described within.

The changes to the indicated files will not yet be reflected in `client` 's connections array when the function returns.

If all of the indicated files were successfully loaded, the function will return `TRUE`, and `failures` will be set to `NULL`. If NetworkManager tried to load the files, but some (or all) failed, then `failures` will be set to a `NULL`-terminated array of the filenames that failed to load.

#### Parameters

client | the `NMClient` |
filenames | `NULL`-terminated array of filenames to load. | [array zero-terminated=1]
failures | on return, a `NULL`-terminated array of filenames that failed to load. | [out][transfer full]
cancellable | a GCancellable, or `NULL` |
error | return location for GError |

#### Returns

`TRUE` on success.

Warning: before libnm 1.22, the boolean return value was inconsistent. That is made worse, because when running against certain server versions before 1.20, the server would return wrong values for success/failure. This means, if you use this function in libnm before 1.22, you are advised to ignore the boolean return value and only look at `failures` and `error` . With libnm >= 1.22, the boolean return value corresponds to whether `error` was set. Note that even in the success case, you might have individual `failures` . With 1.22, the return value is consistent with `nm_client_load_connections_finish()`.

                         gpointer user_data);

Call `g_dbus_connection_call()` on the current name owner with the specified arguments. Most importantly, this invokes `g_dbus_connection_call()` with the client's GMainContext, so that the response is always in order with other events D-Bus events. Of course, the call uses GTask and will invoke the callback on the current `g_main_context_get_thread_default()`.

This API is merely a convenient wrapper for `g_dbus_connection_call()`. You can also use `g_dbus_connection_call()` directly, with the same effect.

#### Parameters

object_path | path of remote object |
interface_name | D-Bus interface to invoke method on |
method_name | the name of the method to invoke |
parameters | a GVariant tuple with parameters for the method or `NULL` if not passing parameters. | [nullable]
reply_type | the expected type of the reply (which will be a tuple), or `NULL`. | [nullable]
timeout_msec | the timeout in milliseconds, -1 to use the default timeout or `G_MAXINT` for no timeout |
cancellable | a GCancellable or `NULL`. | [nullable]

                                 gpointer user_data);

Like `nm_client_dbus_call()` but calls "Set" on the standard "org.freedesktop.DBus.Properties" D-Bus interface.

#### Parameters

client | the NMClient |
object_path | path of remote object |
interface_name | D-Bus interface for the property to set. |
property_name | the name of the property to set |
value | a GVariant with the value to set. |
timeout_msec | the timeout in milliseconds, -1 to use the default timeout or `G_MAXINT` for no timeout |
cancellable | a GCancellable or `NULL`. | [nullable]
callback | a GAsyncReadyCallback to call when the request is satisfied or `NULL` if you don't care about the result of the method invocation. | [nullable]
user_data | the data to pass to `callback` |

### nm_client_dbus_set_property_finish ()

    gboolean
    nm_client_dbus_set_property_finish (NMClient *client,
                                        GAsyncResult *result,
                                        GError **error);

Gets the result of a call to `nm_client_dbus_set_property()`.

#### Parameters

client | the NMClient instance |
result | the result passed to the GAsyncReadyCallback |
error | location for a GError, or `NULL` |

#### Returns

`TRUE` on success or `FALSE` on failure.

### nm_utils_print ()

    void
    nm_utils_print (int output_mode,
                    const char *msg);

The only purpose of this function is to give access to `g_print()` or `g_printerr()` from pygobject. libnm can do debug logging by setting LIBNM_CLIENT_DEBUG and uses thereby `g_printerr()` or `g_print()`. A plain "`print()`" function in python is not in sync with these functions (it implements additional buffering). By using `nm_utils_print()`, the same logging mechanisms can be used.

#### Parameters

output_mode | if 1 it uses `g_print()`. If 2, it uses `g_printerr()`. If 0, it uses either `g_print()` or `g_printerr()`, depending on LIBNM_CLIENT_DEBUG (and the "stdout" flag). |
msg | the message to print. The function does not append a trailing newline. |

Since: 1.30

## Types and Values

### enum NMClientInstanceFlags

#### Members

NM_CLIENT_INSTANCE_FLAGS_NONE | special value to indicate no flags. |
NM_CLIENT_INSTANCE_FLAGS_NO_AUTO_FETCH_PERMISSIONS | by default, NMClient will fetch the permissions via "GetPermissions" and refetch them when "CheckPermissions" signal gets received. By setting this flag, this behavior can be disabled. You can toggle this flag to enable and disable automatic fetching of the permissions. Watch also `nm_client_get_permissions_state()` to know whether the permissions are up to date. |

### enum NMClientError

Describes errors that may result from operations involving a NMClient.

D-Bus operations may also return errors from other domains, including NMManagerError, NMSettingsError, NMAgentManagerError, and NMConnectionError.

#### Members

NM_CLIENT_ERROR_FAILED | unknown or unclassified error |
NM_CLIENT_ERROR_MANAGER_NOT_RUNNING | an operation that requires NetworkManager failed because NetworkManager is not running |
NM_CLIENT_ERROR_OBJECT_CREATION_FAILED | NetworkManager claimed that an operation succeeded, but the object that was allegedly created (eg, NMRemoteConnection, NMActiveConnection) was apparently destroyed before NMClient could create a representation of it. |
