Environment entries should be strings containing a non-empty name and a value separated by a '=' character. The name does not contain a '=' character, so the name is everything up to the first '=' character. Values are everything after the first '=' character. A value may contain further '=' characters, and it may be empty. Returns an [OSError] if retrieving the environment fails."/>
<itemvalue="Creates a new repeating timer. The [callback] is invoked repeatedly with [duration] intervals until canceled with the [cancel] function. The exact timing depends on the underlying timer implementation. No more than `n` callbacks will be made in `duration n` time, but the time between two consecutive callbacks can be shorter and longer than `duration`. In particular, an implementation may schedule the next callback, e.g., a `duration` after either when the previous callback ended, when the previous callback started, or when the previous callback was scheduled for - even if the actual callback was delayed."/>
