int DB->set_re_delim(DB *db, int re_delim);
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 function returns a non-zero error value on failure and 0 on success.
The DB->set_re_delim function may fail and return a non-zero error for the following conditions:
Called after DB->open was called.
The DB->set_re_delim function 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_delim function may fail and return DB_RUNRECOVERY, in which case all subsequent Berkeley DB calls will fail in the same way.
