NAME

       socket_mcttl4 - set multicast ttl

SYNTAX

       #include <libowfat/socket.h>

       int socket_mcttl4(int s,char TTL);

DESCRIPTION

       socket_mcttl4  sets  the  TTL  of outgoing multicast packets on the socket s.  Each router
       decrements the packet TTL by one and discards the packet if the TTL reaches zero.  Setting
       the TTL to 1, for example, will limit the packet propagation to the LAN.

       If something goes wrong, socket_mcttl4 returns -1, setting errno appropriately.
