#include <db.h> int db_sequence_create(DB_SEQUENCE **seq, DB *db, u_int32_t flags);
Creates a sequence handle, which can then be opened with DB_SEQUENCE->open().
DB_SEQUENCE handles are free-threaded if the
DB_THREAD
flag is specified to the
DB_SEQUENCE->open()
method when the sequence is opened. Once the
DB_SEQUENCE->close() or
DB_SEQUENCE->remove()
methods are called, the handle can not be accessed again, regardless
of the method's return.
Each handle opened on a sequence may maintain a separate cache of values which are returned to the application using the DB_SEQUENCE->get() method either singly or in groups depending on its delta parameter.
Calling the DB_SEQUENCE->close() or DB_SEQUENCE->remove() methods discards this handle.
db_sequence_create()
method returns a non-zero error value on failure and 0 on success.
The db parameter is an open database handle which holds the persistent data for the sequence. The database may be of any type, but must not have been configured to support duplicate data items.
The db_sequence_create
method may fail and return one of the following non-zero errors:
