    <title>Description</title>

    <para><filename>sd-journal.h</filename> provides APIs to submit
    and query log entries. The APIs exposed act both as client for the
    <citerefentry><refentrytitle>systemd-journald.service</refentrytitle><manvolnum>8</manvolnum></citerefentry>
    journal service and as parser for the journal files on disk.
