MIB_BEST_IF structure (iprtrmib.h)
The MIB_BEST_IF structure stores the index of the interface that has the best route to a particular destination IPv4 address.
Syntax
typedef struct _MIB_BEST_IF {
DWORD dwDestAddr;
DWORD dwIfIndex;
} MIB_BEST_IF, *PMIB_BEST_IF;
Members
dwDestAddr
Specifies the IPv4 address of the destination.
dwIfIndex
Specifies the index of the interface that has the best route to the destination address specified by the dwDestAddr member.
Remarks
On the Microsoft Windows Software Development Kit (SDK) released for Windows Vista and later, the organization of header files has changed and the MIB_BEST_IF 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.
