RE: UD(datagram) multicasting in ada

[Coker, Jeremy]

Hi, can anyone help me.

I've been using the R.R. Claw package to do UDP datagram send/receive,

The claw package does not seem to include multicasting for UDP (is this 
correct ?0

Otherwise, does anyone have any hints/example of UDP multicasting in ADA ?

  Look at Claw.Sockets.Datagrams.Broadcast

The way I remember it, multicasting involves making some appropriate IOCTL
calls, and then doing normal UDP using the proper IP addresses. There's not
really any Ada-specific issues involved. 

All you have to do is figure out the proper Socket API calls to make (any good
TCP/IP reference should have this info), then translate them into Ada (which is
a fairly trivial step). Is there something specific that you are having trouble
translating?

Claw.Sockets was implemented on top of WinSock 1.1. Multicasting was
introduced with WinSock 2.0, so we didn't look at implementing it. We
could probably look at implementing a multicasting package; is your Claw
support agreement up-to-date??
