<para><function>sd_journal_get_catalog()</function>
|
|
retrieves a message catalog entry for the current
|
|
journal entry. This will look up an entry in the
|
|
message catalog by using the
|
|
<literal>MESSAGE_ID=</literal> 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 it the current
|
|
journal entry the "@" will be removed but the field
|
|
name otherwise left untouched.</para>
|
|
|
|
<para><function>sd_journal_get_catalog_for_message_id()</function>
|
|
works similar to
|
|
<function>sd_journal_get_catalog()</function> but the
|
|
entry is looked up by the specified message ID (no
|
|
open journal context is necessary for this), and no
|
|
field substitution is done.</para>
|
|
|

|
|
catalog please refer to the <ulink
