The Gda_ServerImpl object holds a GList of all open connections for this
provider, so you can just have a global variable of type Gda_ServerImpl
and use this GList. I've added a gda_server_impl_get_connections #define
for that purpose, so use it if you like it.

But, we can also add the function you want, which returns a GList of all
open connections for all Gda_ServerImpl objects (usually there will be
only one per provider/process though). But as there should be only one
Gda_ServerImpl per process, I think the first solution is better.
