SD-JOURNAL(3)			  sd-journal			 SD-JOURNAL(3)

NAME
       sd-journal - APIs for submitting and querying log entries to and from
       the journal

SYNOPSIS
       #include <systemd/sd-journal.h>

       pkg-config --cflags --libs libsystemd

DESCRIPTION
       sd-journal.h provides APIs to submit and query log entries. The APIs
       exposed act both as client for the systemd-journald.service(8) journal
       service and as parser for the journal files on disk.

       See sd_journal_print(3), sd_journal_stream_fd(3), sd_journal_open(3),
       sd_journal_next(3), sd_journal_get_realtime_usec(3),
       sd_journal_add_match(3), sd_journal_seek_head(3),
       sd_journal_get_cursor(3), sd_journal_cutoff_realtime_usec(3),
       sd_journal_get_usage(3), sd_journal_get_catalog(3) and
       sd_journal_get_fd(3) for more information about the functions
       implemented.

       Command line access for submitting entries to the journal is available
       with the systemd-cat(1) tool. Command line access for querying entries
       from the journal is available with the journalctl(1) tool.

NOTES
       These APIs are implemented as a shared library, which can be compiled
       and linked to with the libsystemd pkg-config(1) file.
