  As i already wrote, you should work with Services API. If you never works with it before i suggest to
read IB6 "API Guide"

and corresponding docs for Lazarus access components you used to work with Firebird.

isc_action_svc_trace_* is not a functions exported from DLL.
This is numeric constants (tags) used to work with Services API.

Hope it helps,
