#include <db.h>int DB_ENV->set_lg_dir(DB_ENV *dbenv, const char *dir);
The path of a directory to be used as the location of logging files. Log files created by the Log Manager subsystem will be created in this directory.
If no logging directory is specified, log files are created in the environment home directory. See Berkeley DB File Naming for more information.
For the greatest degree of recoverability from system or application failure, database files and log files should be located on separate physical devices.
The DB_ENV->set_lg_dir interface may be used only to configure Berkeley DB before the DB_ENV->open interface is called.
The DB_ENV->set_lg_dir function returns a non-zero error value on failure and 0 on success.
The database environment's logging directory may also be set using the environment's DB_CONFIG file. The syntax of the entry in that file is a single line with the string "set_lg_dir", one or more whitespace characters, and the directory name. Because the DB_CONFIG file is read when the database environment is opened, it will silently overrule configuration done before that time.
The DB_ENV->set_lg_dir function may fail and return a non-zero error for the following conditions:
Called after DB_ENV->open was called.
The DB_ENV->set_lg_dir function may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions. If a catastrophic error has occurred, the DB_ENV->set_lg_dir function may fail and return DB_RUNRECOVERY, in which case all subsequent Berkeley DB calls will fail in the same way.
