They log a "info" or "warning" prefix string, and use a different
numerical severity:

       LOG_INFO       informational message
       LOG_WARNING    warning conditions

(for other levels see "man 3 syslog").

syslogd(8) and the like can be configured to log different
severity levels to different destinations.
