    NMVpnEditorPlugin *
    (*NMVpnEditorPluginFactory) (GError **error);

### nm_vpn_editor_plugin_factory ()

    NMVpnEditorPlugin *
    nm_vpn_editor_plugin_factory (GError **error);

### nm_vpn_editor_plugin_get_editor ()

    nm_vpn_editor_plugin_get_editor (NMVpnEditorPlugin *plugin,
                                     NMConnection *connection,
                                     GError **error);

### nm_vpn_editor_plugin_get_capabilities ()

    NMVpnEditorPluginCapability
    nm_vpn_editor_plugin_get_capabilities (NMVpnEditorPlugin *plugin);

### nm_vpn_editor_plugin_get_vt ()

    gsize
    nm_vpn_editor_plugin_get_vt (NMVpnEditorPlugin *plugin,
                                 NMVpnEditorPluginVT *vt,
                                 gsize vt_size);

Returns an opaque VT function table for the plugin to extend functionality. The actual meaning of NMVpnEditorPluginVT is not defined in public API of libnm, instead it must be agreed by both the plugin and the caller. See the header-only file 'nm-vpn-editor-plugin-call.h' which defines the meaning.

#### Parameters

plugin | the NMVpnEditorPlugin |
vt | buffer to be filled with the VT table of the plugin. | [out]
vt_size | the size of the buffer. Can be 0 to only query the size of plugin's VT. |

#### Returns

the actual size of the `plugin` 's virtual function table.

                                 GError **error);

#### Parameters

plugin | the NMVpnEditorPlugin |
path | full path to the file to attempt to read into a new NMConnection |
error | on return, an error or `NULL` |

#### Returns

a new NMConnection imported from `path` , or `NULL` on error or if the file at `path` was not recognized by this plugin.

### nm_vpn_editor_plugin_export ()

    gboolean
    nm_vpn_editor_plugin_export (NMVpnEditorPlugin *plugin,
                                 const char *path,
                                 NMConnection *connection,
                                 GError **error);

### nm_vpn_editor_plugin_get_suggested_filename ()

    char *
    nm_vpn_editor_plugin_get_suggested_filename
                                   (NMVpnEditorPlugin *plugin,
                                    NMConnection *connection);

### nm_vpn_editor_plugin_load_from_file ()

    NMVpnEditorPlugin *
    nm_vpn_editor_plugin_load_from_file (const char *plugin_name,
                                         const char *check_service,
                                         int check_owner,
                                         NMUtilsCheckFilePredicate check_file,
                                         gpointer user_data,
                                         GError **error);

Load the shared libary `plugin_name` and create a new NMVpnEditorPlugin instace via the NMVpnEditorPluginFactory function.

If `plugin_name` is not an absolute path name, it assumes the file is in the plugin directory of NetworkManager. In any case, the call will do certain checks on the file before passing it to dlopen. A consequence for that is, that you cannot omit the ".so" suffix as you could for `nm_vpn_editor_plugin_load()`.

#### Parameters

plugin_name | The path or name of the shared library to load. The path must either be an absolute filename to an existing file. Alternatively, it can be the name (without path) of a library in the plugin directory of NetworkManager. |
check_service | if not-null, check that the loaded plugin advertises the given service. |
check_owner | if non-negative, check whether the file is owned by UID `check_owner` or by root. In this case also check that the file is not writable by anybody else. |
check_file | optional callback to validate the file prior to loading the shared library. | [scope call]
user_data | user data for `check_file` |
error | on failure the error reason. |

#### Returns

a new plugin instance or `NULL` on error.

### nm_vpn_editor_plugin_load ()

    NMVpnEditorPlugin *
    nm_vpn_editor_plugin_load (const char *plugin_name,
                               const char *check_service,
                               GError **error);

Load the shared libary `plugin_name` and create a new NMVpnEditorPlugin instace via the NMVpnEditorPluginFactory function.

This is similar to `nm_vpn_editor_plugin_load_from_file()`, but it does no validation of the plugin name, instead passes it directly to `dlopen()`. If you have the full path to a plugin file, `nm_vpn_editor_plugin_load_from_file()` is preferred.

#### Parameters

plugin_name | The name of the shared library to load. This path will be directly passed to `dlopen()` without further checks. |
check_service | if not-null, check that the loaded plugin advertises the given service. |
error | on failure the error reason. |

#### Returns

a new plugin instance or `NULL` on error.

### nm_vpn_editor_plugin_get_plugin_info ()

    struct _NMVpnPluginInfo *
    nm_vpn_editor_plugin_get_plugin_info (NMVpnEditorPlugin *plugin);

#### Parameters

plugin | the NMVpnEditorPlugin instance |

#### Returns

if set, return the NMVpnPluginInfo instance.

[transfer none]

Since: 1.4

### nm_vpn_editor_plugin_set_plugin_info ()

    void
    nm_vpn_editor_plugin_set_plugin_info (NMVpnEditorPlugin *plugin,
                                          struct _NMVpnPluginInfo *plugin_info);

Set or clear the plugin-info instance. This takes a weak reference on `plugin_info` , to avoid circular reference as the plugin-info might also reference the editor-plugin.

#### Parameters

plugin | the NMVpnEditorPlugin instance |
plugin_info | a NMVpnPluginInfo instance or `NULL`. | [allow-none]

Since: 1.4
