log_flush

#include <db.h> int log_flush(DB_ENV *env, const DB_LSN *lsn); Description The log_flush function guarantees that all log records whose DB_LSN values are less than or equal to the lsn argument have been written to disk. If lsn is NULL, all records in the log are flushed. The log_flush function returns a non-zero error value on failure and 0 on success. Errors The log_flush function may fail and return a non-zero error for the following conditions: EINVAL An invalid flag value or parameter was specified. The log_flush 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 log_flush function may fail and return DB_RUNRECOVERY, in which case all subsequent Berkeley DB calls will fail in the same way.
