int DB->set_re_pad(DB *db, int re_pad);
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 returns a non-zero error value on failure and 0 on success.
The DB->set_re_pad method may fail and return a non-zero error for the following conditions:
Called after DB->open was called.
The DB->set_re_pad method may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions. If a catastrophic error has occurred, the DB->set_re_pad method may fail and return DB_RUNRECOVERY, in which case all subsequent Berkeley DB calls will fail in the same way.
