<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.
