Berkeley DB: DB_MPOOLFILE->set_clear_len
|
DB_MPOOLFILE->set_clear_len
|
 |
#include <db.h>
int
DB_MPOOLFILE->set_clear_len(DB_MPOOLFILE *mpf, u_int32_t len);
int
DB_MPOOLFILE->get_clear_len(DB_MPOOLFILE *mpf, u_int32_t *lenp);
Description: DB_MPOOLFILE->set_clear_len
The DB_MPOOLFILE->set_clear_len method 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 clear length is specified, the
entire page is cleared when it is created.
The DB_MPOOLFILE->set_clear_len method configures a file in the memory pool, not only
operations performed using the specified DB_MPOOLFILE handle.
The DB_MPOOLFILE->set_clear_len method may not be called after the DB_MPOOLFILE->open method is
called.
If the file is already open in the memory pool when
DB_MPOOLFILE->open is called, the information specified to DB_MPOOLFILE->set_clear_len
must be consistent with the existing file or an error will be
returned.
The DB_MPOOLFILE->set_clear_len method
returns a non-zero error value on failure
and 0 on success.
Parameters
len- The len parameter is the number of initial bytes in a page that
should be set to nul when the page is created. A value of 0 results in
the entire page being set to nul bytes.
Description: DB_MPOOLFILE->get_clear_len
The DB_MPOOLFILE->get_clear_len method returns the bytes to be cleared.
The DB_MPOOLFILE->get_clear_len method may be called at any time during the life of the
application.
The DB_MPOOLFILE->get_clear_len method
returns a non-zero error value on failure
and 0 on success.
Parameters
lenp- The DB_MPOOLFILE->get_clear_len method returns the
bytes to be cleared in lenp.
Class
DB_ENV, DB_MPOOLFILE
