#include <db.h>int DB_ENV->txn_checkpoint(const DB_ENV *env, u_int32_t kbyte, u_int32_t min, u_int32_t flags);
If there has been any logging activity in the database environment since the last checkpoint, the DB_ENV->txn_checkpoint method flushes the underlying memory pool, writes a checkpoint record to the log, and then flushes the log.
The DB_ENV->txn_checkpoint method returns a non-zero error value on failure and 0 on success.
The DB_ENV->txn_checkpoint method is the underlying method used by the db_checkpoint utility. See the db_checkpoint utility source code for an example of using DB_ENV->txn_checkpoint in a IEEE/ANSI Std 1003.1 (POSIX) environment.
The DB_ENV->txn_checkpoint method may fail and return one of the following non-zero errors:
