int
DB_SEQUENCE->get_flags(DB_SEQUENCE *seq, u_int32_t *flagsp);

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.

• 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.
  
  

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

• An invalid flag value or parameter was specified.

The DB_SEQUENCE->get_flags method returns the current flags.

The DB_SEQUENCE->get_flags method may be called at any time during the life of the application.

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

• The DB_SEQUENCE->get_flags method returns the current flags in flagsp.
