[Winpcap-users] Packet32.h(209) : error C2079: 'IPAddress' uses undefined struct 'sockaddr_storage'

[Vasily Borovyak]

Hi Steven.

Simply try to include *Winsock2.h*.
Here is MSDN:


  SOCKADDR_STORAGE

The *SOCKADDR_STORAGE* structure stores socket address information. 
Since the *SOCKADDR_STORAGE* structure is sufficiently large to store 
IPv4 or IPv6 address information, or others, its use promotes 
protocol-family and protocol-version independence, and simplifies 
cross-platform development. Use the *SOCKADDR_STORAGE* structure in 
place of the *sockaddr* <sockaddr_2.htm> structure.

typedef struct sockaddr_storage {
  short ss_family;
  char __ss_pad1[_SS_PAD1SIZE];
  __int64 __ss_align;
  char __ss_pad2[_SS_PAD2SIZE];
} SOCKADDR_STORAGE, 
*PSOCKADDR_STORAGE;


        Members

*ss_family*
    Address family of the socket, such as AF_INET. 
*__ss_pad1*
    Reserved. Defined as a 48-bit pad that ensures *SOCKADDR_STORAGE*
    achieves 64-bit alignment. 
*__ss_align*
    Reserved. Used by the compiler to align the structure. 
*__ss_pad2*
    Reserved. Used by the compiler to align the structure. 


        Remarks

Application developers use only the *ss_family* member of the 
*SOCKADDR_STORAGE*. The remaining three members ensure the 
*SOCKADDR_STORAGE* is padded appropriately to achieve 64-bit alignment. 
Such alignment enables protocol-specific socket address data structures 
to access fields within a *SOCKADDR_STORAGE* structure without alignment 
problems. With its padding, the *SOCKADDR_STORAGE* structure is 128 
bytes in length.

The member field of the *SOCKADDR_STORAGE* structure is isomorphic with 
the *sockaddr* <sockaddr_2.htm> structure to enable simplified 
transition from sockaddr to *SOCKADDR_STORAGE*.

For more information about platform-independent *SOCKADDR_STORAGE* 
implementation recommendations, refer to RFC 2553, available at 
www.ietf.org <http://www.ietf.org>.


        Requirements

*Client: *Requires Windows XP.
*Server: *Requires Windows Server 2003.
*Header: *Declared in _*Winsock2.h*_.
