  • [アーティクル]

The MCAST_HBEAT_INFO is used for multicast heartbeat information. See [RFC1301] and [RFC3376] for more details.

 typedef struct _MCAST_HBEAT_INFO {
   WCHAR pwszGroup[MAX_GROUP_LEN];
   BOOL bActive;
   ULONG ulDeadInterval;
   BYTE byProtocol;
   WORD wPort;
 } MCAST_HBEAT_INFO,
  *PMCAST_HBEAT_INFO;

pwszGroup: A null-terminated Unicode string that contains the name and address of the multicast group.

bActive: Indicates whether or not the heartbeat is active.

ulDeadInterval: The dead interval in minutes.

byProtocol: Specifies how the heartbeat is being carried out. This MUST have one of the following values.
