The <code class="methodname">DB->get_ext_file_dir()</code> method returns
|
||
the directory location where external file data is stored. The default
|
||
location can be set using <a class="xref" href="set_blob_dir.html" title="DB->set_ext_file_dir()">
|
||
<span>DB->set_ext_file_dir()</span>
|
||
|
||
</a>. Use this method only
|
||
if the database was not opened in an environment. If the database
|
||
was opened within an encompassing environment, use
|
||
<a class="xref" href="envget_blob_dir.html" title="DB_ENV->get_ext_file_dir()">
|
||
<span>DB_ENV->get_ext_file_dir()</span>

|

The <code class="methodname">DB->get_ext_file_dir()</code> method always
|

returns 0 to indicate success.
