Description

Functions

NMVpnEditorPluginFactory ()

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

nm_vpn_editor_plugin_factory ()

NMVpnEditorPlugin *
nm_vpn_editor_plugin_factory (GError **error);

nm_vpn_editor_plugin_get_editor ()

NMVpnEditor *
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.

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`

                             const char *path,

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 library plugin_name and create a new NMVpnEditorPlugin instance 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 library plugin_name and create a new NMVpnEditorPlugin instance 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 ()

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,
                                      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`.	[nullable]

Since: 1.4

Types and Values

enum NMVpnEditorPluginCapability

Flags that indicate certain capabilities of the plugin to editor programs.

Members

NM_VPN_EDITOR_PLUGIN_CAPABILITY_NONE	unknown or no capability
NM_VPN_EDITOR_PLUGIN_CAPABILITY_IMPORT	the plugin can import new connections
NM_VPN_EDITOR_PLUGIN_CAPABILITY_EXPORT	the plugin can export connections
NM_VPN_EDITOR_PLUGIN_CAPABILITY_IPV6	the plugin supports IPv6 addressing

Members

`get_editor` ()	returns an NMVpnEditor, pre-filled with values from `connection` if non-`NULL`.
`get_capabilities` ()	returns a bitmask of capabilities.
`import_from_file` ()	Try to import a connection from the specified path. On success, return a partial NMConnection object. On error, return `NULL` and set `error` with additional information. Note that `error` can be `NULL`, in which case no additional error information should be provided.
`export_to_file` ()	Export the given connection to the specified path. Return `TRUE` on success. On error, return `FALSE` and set `error` with additional error information. Note that `error` can be `NULL`, in which case no additional error information should be provided.
`get_suggested_filename` ()	For a given connection, return a suggested file name. Returned value will be `NULL` or a suggested file name to be freed by the caller.
`notify_plugin_info_set` ()	A callback to be called when the plugin info is set.
`get_vt` ()	return a virtual function table to implement further functions in the plugin, without requiring to update libnm. Used by `nm_vpn_editor_plugin_get_vt()`.
