Where can I get some information on connection pooling in IBObjects?

The only thing I have found so far in the help file and FAQ is a
reference to:
DisconnectToPool.

I am not sure what this does and I do not see any references to a
RetrieveFromPool or ConnectFromPool or???

I am writing a small custom TCPServer to receive a couple of simple
select and insert messages from clients.

Thanks,
Clive.
