Db::set_re_delim

#include <db_cxx.h>
int
Db::set_re_delim(int re_delim);
Description
Set the delimiting byte used to mark the end of a record in the backing
source file for the Recno access method.
This byte is used for variable length records if the re_source
file is specified. If the re_source file is specified and no
delimiting byte was specified, <newline> characters (that
is, ASCII 0x0a) are interpreted as end-of-record markers.
The Db::set_re_delim method configures a database, not only operations performed
using the specified Db handle.
The Db::set_re_delim interface may not be called after the Db::open
interface is called.
If the database already exists when
Db::open is called, the information specified to Db::set_re_delim will
be ignored.
The Db::set_re_delim method either returns a non-zero error value or throws an exception that
encapsulates a non-zero error value on failure, and returns 0 on success.
Errors
The Db::set_re_delim method may fail and throw an exception or return a non-zero error for the following conditions:
- EINVAL
- An invalid flag value or parameter was specified.
Called after Db::open was called.
The Db::set_re_delim method may fail and throw an exception or return a non-zero error for errors specified for other Berkeley DB and C library or system methods.
If a catastrophic error has occurred, the Db::set_re_delim method may fail and
either return DB_RUNRECOVERY or throw a
DbRunRecoveryException,
in which case all subsequent Berkeley DB calls will fail in the same way.
