Re: But my change does not disable the ability to change the
interface from the default. The address parameter on the "bind"
call specifies what destination addresses the socket will accept in
the arriving packets. If you use INADDR_ANY, you can accept data
which specifies any address as the destination address. If you
specifiy ReceivingInterfaceAddr as, for example, 192.168.38.24, then
your socket can ONLY receive data which was sent with 192.168.38.24
as the destination. Data sent to that socket with a multicast
address won't be received.
I don't whether or not this is universal behavior, or just something
that's peculiar to your OS. In any case, the current code
("bind()"ing to "ReceivingInterfaceAddr") is necessary for unicast
streams to work properly (if "ReceivingInterfaceAddr" was set to
something other than INADDR_ANY).
The best way to control the interface on which you receive multicast
packets is to ensure that the OS has a proper route for multicast
packets on that interface.
