## 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.

### Class
