#include <db.h>int DB_ENV->set_mp_max_write(DB_ENV *env, int maxwrite, int maxwrite_sleep);
int DB_ENV->get_mp_max_write(DB_ENV *env, int *maxwritep, int *maxwrite_sleepp);
The DB_ENV->set_mp_max_write method limits the number of sequential write operations scheduled by the library when flushing dirty pages from the cache.
The DB_ENV->set_mp_max_write method returns a non-zero error value on failure and 0 on success.
The DB_ENV->set_mp_max_write method may fail and return one of the following non-zero errors:
The DB_ENV->get_mp_max_write method returns the current maximum number of sequential write operations and microseconds to pause.
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.
