#include <db_cxx.h> int DbEnv::get_ext_file_dir(const char **dirp);
The DbEnv::get_ext_file_dir() method returns
the directory location where external file data is stored. The default
location can be set using
DbEnv::set_ext_file_dir()
. Use this method only
if the database was opened in an environment. If the database
was not opened within an encompassing environment, use
Db::get_ext_file_dir()
instead.
The DbEnv::get_ext_file_dir() method always
returns 0 to indicate success.
The dirp parameter references memory into which is copied the path to the external file data directory. If DbEnv::set_ext_file_dir() has not been called prior to calling this method, or if external files are notsupported by this environment, then this parameter is set to NULL.
