Methods Summary
public static native int	hops(long sock, int ttl) Set the Multicast Time to Live (ttl) for a multicast transmission. param sock The socket to set the multicast ttl param ttl Time to live to Assign. 0-255, default=1 Remark : If the TTL is 0, packets will only be seen by sockets on the local machine, and only when multicast loopback is enabled.
public static native int	join(long sock, long join, long iface, long source) Join a Multicast Group param sock The socket to join a multicast group param join The address of the multicast group to join param iface Address of the interface to use. If NULL is passed, the default multicast interface will be used. (OS Dependent) param source Source Address to accept transmissions from (non-NULL implies Source-Specific Multicast)
public static native int	leave(long sock, long addr, long iface, long source) Leave a Multicast Group. All arguments must be the same as apr_mcast_join. param sock The socket to leave a multicast group param addr The address of the multicast group to leave param iface Address of the interface to use. If NULL is passed, the default multicast interface will be used. (OS Dependent) param source Source Address to accept transmissions from (non-NULL implies Source-Specific Multicast)
public static native int	loopback(long sock, boolean opt) Toggle IP Multicast Loopback param sock The socket to set multicast loopback param opt false=disable, true=enable
public static native int	ointerface(long sock, long iface) Set the Interface to be used for outgoing Multicast Transmissions. param sock The socket to set the multicast interface on param iface Address of the interface to use for Multicast
