The MIB_IFROW structure stores information about a particular interface.
Type: WCHAR[MAX_INTERFACE_NAME_LEN]
A pointer to a Unicode string that contains the name of the interface.
Type: DWORD
The index that identifies the interface. This index value may change when a network adapter is disabled and then enabled, and should not be considered persistent.
Type: DWORD
The interface type as defined by the Internet Assigned Names Authority (IANA). For more information, see http://www.iana.org/assignments/ianaiftype-mib. Possible values for the interface type are listed in the Ipifcons.h header file.
The table below lists common values for the interface type although many other values are possible.
Type: DWORD
The Maximum Transmission Unit (MTU) size in bytes.
Type: DWORD
The speed of the interface in bits per second.
Type: DWORD
The length, in bytes, of the physical address specified by the bPhysAddr member.
Type: BYTE[MAXLEN_PHYSADDR]
The physical address of the adapter for this interface.
Type: DWORD
The interface is administratively enabled or disabled.
Type: DWORD
The operational status of the interface. This member can be one of the following values defined in the INTERNAL_IF_OPER_STATUS enumeration defined in the Ipifcons.h header file.
Type: DWORD
The length of time, in hundredths of seconds (10^-2 sec), starting from the last computer restart, when the interface entered its current operational state. This value rolls over after 2^32 hundredths of a second.
The dwLastChange member is not currently supported by NDIS. On Windows Vista and later, NDIS returns zero for this member. On earlier versions of Windows, an arbitrary value is returned in this member for the interfaces supported by NDIS. For interfaces supported by other interface providers, they might return an appropriate value.
Type: DWORD
The number of octets of data received through this interface.
Type: DWORD
The number of unicast packets received through this interface.
Type: DWORD
The number of non-unicast packets received through this interface. Broadcast and multicast packets are included.
Type: DWORD
The number of incoming packets that were discarded even though they did not have errors.
Type: DWORD
The number of incoming packets that were discarded because of errors.
Type: DWORD
The number of incoming packets that were discarded because the protocol was unknown.
Type: DWORD
The number of octets of data sent through this interface.
Type: DWORD
The number of unicast packets sent through this interface.
Type: DWORD
The number of non-unicast packets sent through this interface. Broadcast and multicast packets are included.
Type: DWORD
The number of outgoing packets that were discarded even though they did not have errors.
Type: DWORD
The number of outgoing packets that were discarded because of errors.
Type: DWORD
The transmit queue length. This field is not currently used.
Type: DWORD
The length, in bytes, of the bDescr member.
Type: BYTE[MAXLEN_IFDESCR]
A description of the interface.
The dwSpeed member of the MIB_IFROW structure will be incorrect for very high-speed network interfaces (10 Gbit/s network adapter, for example) since the maximum value that can be store in a DWORD is 4,294,967,295. Applications should use the MIB_IF_ROW2 structure returned by the GetIfEntry2 and GetIfTable2 functions or the IP_ADAPTER_ADDRESSES structure returned by the GetAdaptersAddresses function for determining the speed for very high-speed network interfaces.
On the Microsoft Windows Software Development Kit (SDK) released for Windows Vista and later, the organization of header files has changed and the MIB_IFROW structure is defined in the Ifmib.h header file not in the Iprtrmib.h header file. Note that the Ifmib.h header file is automatically included in Iprtrmib.h which is automatically included in the Iphlpapi.h header file. The Ifmib.h and Iprtrmib.h header files should never be used directly.
