socket_mcttl4(3)	    Library Functions Manual		socket_mcttl4(3)

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  appropri-
     ately.
