NAME         top

       sd_journal_get_catalog, sd_journal_get_catalog_for_message_id -
       Retrieve message catalog entry

SYNOPSIS         top

       #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         top

       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         top

       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         top

       Function sd_journal_get_catalog() is thread-agnostic and only a
       single thread may operate on a given sd_journal object. Function
       sd_journal_get_catalog_for_message_id() is thread-safe.

       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.
