Berkeley DB: Db::set_re_delim
Db::set_re_delim
|
 |
#include <db_cxx.h>
int
Db::set_re_delim(int re_delim);
int
Db::get_re_delim(int *delimp);
Description: Db::set_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 method configures a database, not only operations performed
using the specified Db handle.
The Db::set_re_delim method may not be called after the Db::open method 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.
Parameters
- re_delim
- The re_delim parameter is the delimiting byte used to mark the
end of a record.
Errors
The Db::set_re_delim method
may fail and throw
DbException,
encapsulating one of the following non-zero errors, or return one of
the following non-zero errors:
- EINVAL
- If the method was called after Db::open was called; or if an
invalid flag value or parameter was specified.
Description: Db::get_re_delim
The Db::get_re_delim method returns the delimiting byte.
The Db::get_re_delim method may be called at any time during the life of the
application.
The Db::get_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.
Parameters
- delimp
- The Db::get_re_delim method returns the
delimiting byte in delimp.
