NAME
socket_mchopcount6 - set multicast hop count
SYNTAX
#include <socket.h>
int socket_mchopcount6(int s,char TTL);
DESCRIPTION
socket_mchopcount6 sets the maximum hop count of outgoing multicast
packets on the socket s. Each router decrements the packet hop count
by one and discards the packet if it reaches zero. Setting the maximum
hop count to 1, for example, will limit the packet propagation to the
LAN.
If something goes wrong, socket_mchopcount6 returns -1, setting errno
appropriately.
