struct in_addr imr_multiaddr; /* IP multicast group address */
struct in_addr imr_address; /* IP address of local interface */
int imr_ifindex; /* interface index */
};
struct ip_mreq {
struct in_addr imr_multiaddr; /* IP multicast group address */
struct in_addr imr_address; /* IP address of local interface */ };

Overview
- .imr_multiaddr
-
The address of the multicast group the application wants to join or leave. It must be a valid multicast address.
- .imr_address
-
The address of the local interface with which the system should join the multicast group; if it is equal to
INADDR_ANY, an appropriate interface is chosen by the system.
- .imr_ifindex
-
The interface index of the interface that should join/leave the .imr_multiaddr group, or 0 to indicate any interface.
