DB_SEQUENCE->set_flags()

#include <db.h>

int
DB_SEQUENCE->set_flags(DB_SEQUENCE *seq, u_int32_t flags);

Configure a sequence. The flags are only effective when creating a sequence. Calling DB_SEQUENCE->set_flags() is additive; there is no way to clear flags.

The DB_SEQUENCE->set_flags() method may not be called after the DB_SEQUENCE->open() method is called.

The DB_SEQUENCE->set_flags() 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_SEQ_DEC

Specify that the sequence should be decremented.
DB_SEQ_INC

Specify that the sequence should be incremented. This is the default.
DB_SEQ_WRAP

Specify that the sequence should wrap around when it is incremented (decremented) past the specified maximum (minimum) value.

Errors

The DB_SEQUENCE->set_flags() method may fail and return one of the following non-zero errors:

EINVAL

An invalid flag value or parameter was specified.
