IP_ADAPTER_ORDER_MAP structure (ipexport.h)

  • Article

The IP_ADAPTER_ORDER_MAP structure stores an array of information about adapters and their relative priority on the local computer.

Syntax

typedef struct _IP_ADAPTER_ORDER_MAP {
  ULONG NumAdapters;
  ULONG AdapterOrder[1];
} IP_ADAPTER_ORDER_MAP, *PIP_ADAPTER_ORDER_MAP;

Members

NumAdapters

The number of network adapters in the AdapterOrder member.

AdapterOrder[1]

An array of adapter indexes on the local computer, provided in the order specified in the Adapters and Bindings dialog box for Network Connections.

Remarks

This structure is returned by the GetAdapterOrderMap function, and is used as a tie breaker for otherwise equal interfaces during network operations. The GetAdapterOrderMap function should not be called directly; use the GetAdaptersInfo function instead.

The IP_ADAPTER_ORDER_MAP structure contains at least one AdapterOrder member even if the NumAdapters member of the IP_ADAPTER_ORDER_MAP structure indicates no network adapters. When the NumAdapters member of the IP_ADAPTER_ORDER_MAP structure is zero, the value of the single AdapterOrder member is undefined.

This structure is defined in the Ipexport.h header file which is automatically included in the Iphlpapi.h header file. The Ipexport.h header file should never be used directly.
