sd_journal_get_catalog, sd_journal_get_catalog_for_message_id — Retrieve message catalog entry
retrieves a message catalog entry for the current
journal entry. This will look up an entry in the
message catalog by using the
MESSAGE_ID=" field of the current
journal entry. Before returning the entry all journal
field names in the catalog entry text enclosed in "@"
will be replaced by the respective field values of the
current entry. If a field name referenced in the
message catalog entry does not exist, in the current
journal entry, the "@" will be removed, but the field
name otherwise left untouched.
