Routine Description:
Given an IHNetConnection, determines the what connections may
serve as a private connection. Only connections that meet the
following criteria may serve as a private connection:
* it's a LAN connection
* it's not part of a bridge
* it's not firewalled
* it's not the connection passed in
* it's bound to TCP/IP
Note that these are not the same rules that are used to set the
fCanBeIcsPrivate member in HNET_CONN_PROPERTIES. In particular,
these rules don't take into account whether or not a connection
is currently marked as IcsPublic.
Arguments:
pConn - the connection that would be the public connection
pcPrivateConnections - receives the count of connections returned
pprgPrivateConnections - receives that possible private connections.
The caller is responsible for:
1) Releasing all of the interface pointers w/in the array
2) Calling CoTaskMemFree on the pointer to the array
pxCurrentPrivate - receives the index into pprgPrivateConnections of
the connection that is currently marked IcsPrivate. If no connection
is so marked, receives -1.
Return Value:
