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. SEE ALSO socket_mcttl6(3), socket_mcjoin4(3), socket_mcleave4(3) socket_mcttl4(3)
