void g_settings_backend_keys_changed ( GSettingsBackend* backend, const gchar* path, const gchar* const* items, gpointer origin_tag )
Signals that a list of keys have possibly changed. Backend implementations should call this if keys have possibly changed their values.
path must be a valid path (ie starting and ending with a slash and
not containing ‘//’). Each string in
items must form a valid key
path is prefixed to it (ie: each item must not start or
end with ‘/’ and must not contain ‘//’).
The meaning of this signal is that any of the key names resulting
from the contatenation of
path with each item in
items may have changed.
The same rules for when notifications must occur apply as per
g_settings_backend_changed(). These two calls can be used
interchangeably if exactly one item has changed (although in that
g_settings_backend_changed() is definitely preferred).
For efficiency reasons, the implementation should strive for
be as long as possible (ie: the longest common prefix of all of the
keys that were changed) but this is not strictly required.
The path containing the changes.
