"NetworkManager.h"'s name (and non-standard capitalization) suggest that it's some sort of high-level super-important header, but it's really just low-level D-Bus stuff. Rename it to "nm-dbus-interface.h" and likewise "NetworkManagerVPN.h" to "nm-vpn-dbus-interface.h"

* @Short_description: A helper for NetworkManager's settings API
|
|
* @Title: NMRemoteSettings
|
|
* @See_also:#NMRemoteConnection, #NMClient
|
|
*
|
|
* The #NMRemoteSettings object represents NetworkManager's "settings" service,
|
|
* which stores network configuration and allows authenticated clients to
|
|
* add, delete, and modify that configuration. The data required to connect
|
|
* to a specific network is called a "connection" and encapsulated by the
|
|
* #NMConnection object. Once a connection is known to NetworkManager, having
|
|
* either been added by a user or read from on-disk storage, the
|
|
* #NMRemoteSettings object creates a #NMRemoteConnection object which
|
|
* represents this stored connection. Use the #NMRemoteConnection object to
|
|
* perform any operations like modification or deletion.
|
|
*
|
|
* To add a new network connection to the NetworkManager settings service, first
|
|
* build up a template #NMConnection object. Since this connection is not yet
|
|
* added to NetworkManager, it is known only to your program and is not yet
|
|
* an #NMRemoteConnection. Then ask #NMRemoteSettings to add your connection.
|
|
* When the connection is added successfully, the supplied callback is called
|
|
* and returns to your program the new #NMRemoteConnection which represents
|
|
* the stored object known to NetworkManager.
