Hi guys!
I'm playing with multicasting (-stable), and I want to disable looping back
my outgoing packets setting IP_MULTICAST_LOOP option to 0 but it doen't
have any effect. My app is listening to the same group it is casting.
After some grepping I came across some code in netinet/ip_output.c:
(imo == NULL || imo->imo_multicast_loop)) {
/*
* If we belong to the destination multicast group
* on the outgoing interface, and the caller did not
* forbid loopback, loop back a copy.
*/
The comment says 'and' but the code says '||' -- looks like an error to me.
Except this I've got no idea what it means - does it make amy sence?

Thanks,
Vadim
