keys_changed
Description:
[ Version ( since = "2.26" ) ]
public void keys_changed (string path, string[] items, void* 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 name when 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 changed. These two calls can be used interchangeably if exactly one item has changed (although in that case changed is definitely preferred).
For efficiency reasons, the implementation should strive for path to be as long as possible (ie: the longest common prefix of all
of the keys that were changed) but this is not strictly required.
Parameters:
| this |
a SettingsBackend implementation |
| path |
the path containing the changes |
| items |
the null-terminated list of changed keys |
| origin_tag |
the origin tag |
