Method Detail

join
public static int join(long sock, long join, long iface, long source)
Join a Multicast Group- Parameters:
sock
- The socket to join a multicast groupjoin
- The address of the multicast group to joiniface
- Address of the interface to use. If NULL is passed, the default multicast interface will be used. (OS Dependent)source
- Source Address to accept transmissions from (non-NULL implies Source-Specific Multicast)- Returns:
- the operation status
-
leave
public static int leave(long sock, long addr, long iface, long source)
Leave a Multicast Group. All arguments must be the same as apr_mcast_join.- Parameters:
sock
- The socket to leave a multicast groupaddr
- The address of the multicast group to leaveiface
- Address of the interface to use. If NULL is passed, the default multicast interface will be used. (OS Dependent)source
- Source Address to accept transmissions from (non-NULL implies Source-Specific Multicast)- Returns:
- the operation status
-
hops
public static int hops(long sock, int ttl)
Set the Multicast Time to Live (ttl) for a multicast transmission.- Parameters:
sock
- The socket to set the multicast ttlttl
- 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.- Returns:
- the operation status
-
loopback
public static int loopback(long sock, boolean opt)
Toggle IP Multicast Loopback- Parameters:
sock
- The socket to set multicast loopbackopt
- false=disable, true=enable- Returns:
- the operation status
-
ointerface
public static int ointerface(long sock, long iface)
Set the Interface to be used for outgoing Multicast Transmissions.- Parameters:
sock
- The socket to set the multicast interface oniface
- Address of the interface to use for Multicast- Returns:
- the operation status
