###

    #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 interface may be used only to configure Berkeley DB before the Db::open interface is called.

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 an exception encapsulating DB_RUNRECOVERY, in which case all subsequent Berkeley DB calls will fail in the same way.
