While the datasets do keep various link lists, those lists are held
internally and cannot be accessed outside the class or derivation.
However...

TIB_Connection keeps several lists of components, see the properties
Datasets, DatasetCount, Statements and StatementCount. So in your
instance I would do something like...

with TIB_Connection do
begin
for i := 0 to DatasetCount - 1 do
begin
if Datasets[i].KeySource = MyDataSource then
<whatever it is you want to do>
end;
end;
