I'm trying to make this work as you suggest. It's pretty clear that all the callbacks should be modified to send a void* along with the other arguments. This would eliminate the need for hookname there (getting the state inside callback functions). The problem is the functions PQhookData(conn, hookname) and PQresultHookData(result, hookName). We need these to work in functions that are not callbacks. If we eliminate hookname completely, there is no way for libpq to know which private state we are asking for. I'm a little bit stuck here. Is it possible to preserve the hookname outside of the context of the callback functions or is there something else I'm missing? (I'm sorry if I'm being obtuse) Eliminating the need for libpqtypes to need PQhookx functions, while possible, would make libpqtypes a lot more difficult to use and generally more awkward. merlin -- Sent via pgsql-patches mailing list (pgsql-patches@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-patches
