| Example: polling for journal events |
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
| |
| This example shows that journal events can be waited for (using |
| e.g. `poll`). This makes it easy to integrate Reader in an external |
| event loop: |
| |
| >>> import select |
| >>> from systemd import journal |
| >>> j = journal.Reader() |
| >>> j.seek_tail() |
| >>> p = select.poll() |
| >>> p.register(j, j.get_events()) |
| >>> p.poll() |
| [(3, 1)] |
| >>> j.get_next() |
| |
