NAME

       sd_journal_get_catalog, sd_journal_get_catalog_for_message_id - Retrieve message catalog entry

SYNOPSIS

       #include <systemd/sd-journal.h>

       int sd_journal_get_catalog(sd_journal *j, char **ret);

       int sd_journal_get_catalog_for_message_id(sd_id128_t id, char **ret);

DESCRIPTION

       sd_journal_get_catalog() 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.

       sd_journal_get_catalog_for_message_id() works similar to sd_journal_get_catalog() but the entry is looked
       up by the specified message ID (no open journal context is necessary for this), and no field substitution
       is performed.

       For more information about the journal message catalog please refer to the Journal Message Catalogs[1]
       documentation page.

RETURN VALUE

       sd_journal_get_catalog() and sd_journal_get_catalog_for_message_id() return 0 on success or a negative
       errno-style error code. If no matching message catalog entry is found, -ENOENT is returned.

       On successful return, ret points to a new string, which must be freed with free(3).

NOTES

       The sd_journal_get_catalog() and sd_journal_get_catalog_for_message_id() interfaces are available as a
       shared library, which can be compiled and linked to with the libsystemd pkg-config(1) file.
