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.
