Other functions — those that are used to send entries to the journal, like + sd_journal_print3 and similar, + or those that are used to retrieve global information like + sd_journal_stream_fd3 and + sd_journal_get_catalog_for_message_id3 + — are fully thread-safe and may be called from multiple threads in parallel. + + + + + + See Also + + systemd1, + sd_journal_print3, + sd_journal_stream_fd3, + sd_journal_open3, + sd_journal_next3, + sd_journal_get_data3, + sd_journal_get_realtime_usec3, + sd_journal_add_match3, + sd_journal_seek_head3, + sd_journal_enumerate_fields3, + sd_journal_get_cursor3, + sd_journal_get_cutoff_realtime_usec3, + sd_journal_get_cutoff_monotonic_usec3, + sd_journal_get_usage3, + sd_journal_get_fd3, + sd_journal_query_unique3, + sd_journal_get_catalog3, + sd_journal_has_runtime_files3, + sd_journal_has_persistent_files3, + journalctl1, + sd-id1283, + pkg-config1 + + + + -- cgit v1.2.3
