DB_ENV->get_mp_max_write(DB_ENV *env, int *maxwritep, 
                         db_timeout_t *maxwrite_sleepp);

The DB_ENV->get_mp_max_write() method returns the current maximum number of sequential write operations and microseconds to pause that the library can schedule when flushing dirty pages from the cache. These values are set by the DB_ENV->set_mp_max_write() method.

The DB_ENV->get_mp_max_write() method may be called at any time during the life of the application.

The DB_ENV->get_mp_max_write() method returns a non-zero error value on failure and 0 on success.
