2.2.1.2.171 IGMP_MIB_GET_INPUT_DATA

The IGMP_MIB_GET_INPUT_DATA structure is passed as input data for the following methods:

• RMIBEntryGet (section 3.1.4.30) 

• RMIBEntryGetFirst (section 3.1.4.31) 

• RMIBEntryGetNext (section 3.1.4.32) 

All IP addresses MUST be in network order.

TypeID: Specifies the type of entry being requested. It MUST be one of the following, otherwise an error is returned.

Value	Meaning
IGMP_IF_STATS_ID 0x00000004	The Internet Group Management Protocol (IGMP) statistics for an interface. If TypeID is set to this value, Count MUST be nonzero.
IGMP_IF_GROUPS_LIST_ID 0x00000005	The list of multicast group members on an interface. If TypeID is set to this value, Count MUST be nonzero.
IGMP_GROUP_IFS_LIST_ID 0x00000006	The list of interfaces joined for a group. If TypeID is set to this value, Count MUST be nonzero and GroupAddr MUST match a valid existing IGMP group address.
IGMP_PROXY_IF_INDEX_ID 0x00000007	Returns the index of the interface owned by the IGMP proxy. RMIBEntryGetNext is invalid as there is only one proxy interface and ERROR_NO_MORE_ITEMS is returned.

Flags: This MUST be one of the following combinations, otherwise an error is returned.

Value	Meaning
IGMP_ENUM_FOR_RAS_CLIENTS 0x00000001	Enumerate for RAS clients only.
IGMP_ENUM_ONE_ENTRY 0x00000002	Return only one interface group entry.
IGMP_ENUM_ALL_INTERFACES_GROUPS 0x00000004	Enumerate all interfaces. If enumeration reaches end of an interface, it will go to the next interface.
IGMP_ENUM_ALL_TABLES 0x00000010	Enumerate all tables.
IGMP_ENUM_SUPPORT_FORMAT_IGMPV3 0x00000010	Set if IGMPv3 is supported.

Signature: This MUST be set to zero (0).

IfIndex: The index of the interface for which information needs to be retrieved.

RasClientAddr: The address of the RAS client for which information needs to be retrieved.

GroupAddr: The IGMP group address for which information needs to be retrieved.

Count: The count of entries that need to be retrieved.
