DB_MPOOLFILE->set_clear_len

 APIRef 

#include <db.h>


int
DB_MPOOLFILE->set_clear_len(DB_MPOOLFILE *mpf, u_int32_t len);

Description

The DB_MPOOLFILE->set_clear_len function sets the number of initial bytes in a page that should be set to nul when the page is created as a result of the DB_MPOOL_CREATE or DB_MPOOL_NEW flags being specified to DB_MPOOLFILE->get. If no value is specified, or len is 0, the entire page is cleared.

The DB_MPOOLFILE->set_clear_len function returns a non-zero error value on failure and 0 on success.

Errors

The DB_MPOOLFILE->set_clear_len 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_MPOOLFILE->set_clear_len function may fail and return DB_RUNRECOVERY, in which case all subsequent Berkeley DB calls will fail in the same way.
