###

    #include <db_cxx.h>

    int
    Db::set_re_pad(int re_pad);

# Description

Set the padding character for short, fixed-length records for the Queue and Recno access methods.

If no pad character is specified, <space> characters (that is, ASCII 0x20) are used for padding.

The Db::set_re_pad method configures a database, not only operations performed using the specified Db handle.

The Db::set_re_pad 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_pad will be ignored.

The Db::set_re_pad 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_pad 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_pad 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_pad 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.
