HowTo - Multicast in VASmalltalk anyone ?

[marten]

I'm building an application, which wants to receive messages, which other application (C# based) are sending over multicast to my subnet. Does anybody know, how to build a multicast server/client in VASMalltalk .... ???

Not defined in the Sci Constants (here the value for Windows) ... perhaps nice to add with the product

#define IP_MULTICAST_LOOP 4 /* set/get IP multicast loopback */

Ok - some code published at http://vastgoodies.com/maps/MSKUDPMulticast and an example at http://www.schrievkrom.de/blog/?p=539

Perhaps some people might not have heard of "multicast". We wrote a C# application - consisting of multiple application - and all participate in a multicast group and send their application specific short data datagram. With that feature we are able to recognize our running applications (especially the servers) and application may find each other.

Be aware of routing problems using multicast.
