    nm_client_get_all_devices (NMClient *client);

Gets both real devices and device placeholders (eg, software devices which do not currently exist, but could be created automatically by NetworkManager if one of their NMDevice::ActivatableConnections was activated). Use `nm_device_is_real()` to determine whether each device is a real device or a placeholder.

Use `nm_device_get_type()` or the `NM_IS_DEVICE_XXXX()` functions to determine what kind of device each member of the returned array is, and then you may use device-specific methods such as `nm_device_ethernet_get_hw_address()`.

[transfer none]

### nm_client_activate_connection_async ()

    void
    nm_client_activate_connection_async (NMClient *client,
                                         NMConnection *connection,
                                         NMDevice *device,
                                         const char *specific_object,
                                         GCancellable *cancellable,
                                         GAsyncReadyCallback callback,
                                         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 used 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 ()

    NMActiveConnection *
    nm_client_activate_connection_finish (NMClient *client,
                                          GAsyncResult *result,
                                          GError **error);

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

#### Parameters

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

#### Returns

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

                                    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.

#### 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 (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` |

                                    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` |

                                GError **error);

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.
