An SPB is a Service Parameter Buffer; you (or the connectivity layer)
can set one up to supply parameters to service API calls.

There are many spb constants, defined in ibase.h: isc_spb_version,
isc_spb_user_name, isc_spb_bkp_file, etc. etc.

If you don't call API functions yourself, you should never have to
deal with them. Maybe something wrong in IBOAdmin?

BTW, if you only need IBOAdmin for backup/restore or user
verification, you might as well pick up the free functions at
