MIB_IPADDRROW_W2K structure (ipmib.h)

The MIB_IPADDRROW specifies information for a particular IPv4 address in the MIB_IPADDRTABLE structure.

Syntax

typedef struct _MIB_IPADDRROW_W2K {
  DWORD          dwAddr;
  DWORD          dwIndex;
  DWORD          dwMask;
  DWORD          dwBCastAddr;
  DWORD          dwReasmSize;
  unsigned short unused1;
  unsigned short unused2;
} MIB_IPADDRROW_W2K, *PMIB_IPADDRROW_W2K;

Members

dwAddr

Type: DWORD

The IPv4 address in network byte order.

dwIndex

Type: DWORD

The index of the interface associated with this IPv4 address.

dwMask

Type: DWORD

The subnet mask for the IPv4 address in network byte order.

dwBCastAddr

Type: DWORD

The broadcast address in network byte order. A broadcast address is typically the IPv4 address with the host portion set to either all zeros or all ones.

The proper value for this member is not returned by the GetIpAddrTable function.

dwReasmSize

Type: DWORD

The maximum re-assembly size for received datagrams.

unused1

Type: unsigned short

This member is reserved.

unused2

Type: unsigned short

This member is reserved.

Remarks

On Windows XP and later, the dwIndex member of the MIB_IPADDRROW structure has a data type of IF_INDEX. The wType member is only available on Windows XP and later. On Windows 2000 and earlier, this member is defined as Unused2.

The GetIpAddrTable function retrieves the interface–to–IPv4 address mapping table on a local computer and returns this information in an MIB_IPADDRTABLE structure. The table member in the MIB_IPADDRTABLE structure contains an array of MIB_IPADDRROW entries.

On the Microsoft Windows Software Development Kit (SDK) released for Windows Vista and later, the organization of header files has changed and the MIB_IPADDRROW structure is defined in the Ipmib.h header file not in the Iprtrmib.h header file. Note that the Ipmib.h header file is automatically included in Iprtrmib.h which is automatically included in the Iphlpapi.h header file. The Ipmib.h and Iprtrmib.h header files should never be used directly.

Examples

To view an example that retrieves the MIB_IPADDRTABLE structure and then prints out the MIB_IPADDRROW structures in this table, see the GetIpAddrTable function.
