#include <db.h>

int
DB->set_re_len(DB *db, u_int32_t re_len);

Description

For the Queue access method, specify that the records are of length re_len.

For the Recno access method, specify that the records are fixed-length, not byte delimited, and are of length re_len.

Any records added to the database that are less than re_len bytes long are automatically padded (see DB->set_re_pad for more information).

Any attempt to insert records into the database that are greater than re_len bytes long will cause the call to fail immediately and return an error.

The DB->set_re_len interface may only be used to configure Berkeley DB before the DB->open interface is called.

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

Errors

EINVAL

An invalid flag value or parameter was specified.

Called after DB->open was called.
