SD_JOURNAL_GET_CATALOG(3) sd_journal_get_catalog SD_JOURNAL_GET_CATALOG(3)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);
DESCRIPTIONsd_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 VALUEsd_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.
