multicast receiver

does anyboby has programmed a multicast datagrams receiver for qnx 4.25 (tcp/ip v5)? does exist any special configuration that i have to concider?

i’m just trying to read packets published to the 224.0.7.1 address. The sender is in the same LAN than the receiver.

thanks for any help!

You need a route to the multicast address, that’s about it as far as external config goes (obviously the code for a multicast receiver is a little different than for a vanilla UDP receiver).

how do i do that?

in linux:

route add 224.0.0.0 netmask 240.0.0.0 dev eth0

but qnx?! how?!
