    #include <db.h>

    int
    DBcursor->c_dup(DBC *DBcursor, DBC **cursorp, u_int32_t flags);

### Description: DBcursor->c_dup

The DBcursor->c_dup method creates a new cursor that uses the same transaction and locker ID as the original cursor. This is useful when an application is using locking and requires two or more cursors in the same thread of control.

The DBcursor->c_dup method returns a non-zero error value on failure and 0 on success.

### Parameters

flags
  The flags parameter must be set to 0 or by bitwise inclusively OR'ing together one or more of the following values:
  DB_POSITION
    The newly created cursor is initialized to refer to the same position in the database as the original cursor (if any) and hold the same locks (if any). If the DB_POSITION flag is not specified, or the original cursor does not hold a database position and locks, the created cursor is uninitialized and will behave like a cursor newly created using DB->cursor.

### Errors

The DBcursor->c_dup method may fail and return one of the following non-zero errors:

DB_REP_HANDLE_DEAD
  The database handle has been invalidated because a replication election unrolled a committed transaction.

EINVAL
  An invalid flag value or parameter was specified.
