INTERFACE_INFO Structure

  • Artikel

The INTERFACE_INFO structure is used in conjunction with the SIO_GET_INTERFACE_LIST ioctl command to obtain information about an interface IP address.

Syntax

typedef struct _INTERFACE_INFO {
  u_long       iiFlags;
  sockaddr_gen iiAddress;
  sockaddr_gen iiBroadcastAddress;
  sockaddr_gen iiNetmask;
} INTERFACE_INFO, FAR * LPINTERFACE_INFO;

Mitglieder

  • iiFlags
    A bitmask describing the status of the interface. The following flags are possible.

    Flag Bedeutung

Hinweise

On the Microsoft Windows Software Development Kit (SDK) released for Windows Vista and later, the organization of header files has changed and the INTERFACE_INFO structure is defined in the Ws2ipdef.h header file which is automatically included in the Ws2tcpip.h header file. The Ws2ipdef.h header files should never be used directly.
