sockaddr_storage结构在什么头文件里定义？

[ailina]

在编写网络编程程序时，遇到以下问题：
#include "packet32.h"
#include "ntddndis.h"
#include <stdio.h>
#include <conio.h>
#include <winsock2.h>
#include <windows.h>

#pragma comment(lib,"ws2_32")
#pragma comment(lib,"packet")
已包含以上文件


c:\program files\microsoft visual studio\vc98\include\packet32.h(204) : error
C2079: 'IPAddress' uses undefined struct 'sockaddr_storage'

c:\program files\microsoft visual studio\vc98\include\packet32.h(205) : error C2079: 'SubnetMask' uses undefined struct 'sockaddr_storage'

c:\program files\microsoft visual studio\vc98\include\packet32.h(206) : error C2079: 'Broadcast' uses undefined struct 'sockaddr_storage'

这是Packet32.h里的代码：
typedef struct npf_if_addr {
struct sockaddr_storage IPAddress; ///< IP address.
struct sockaddr_storage SubnetMask; ///< Netmask for that address.
struct sockaddr_storage Broadcast; ///< Broadcast address.
}npf_if_addr;

#include <winsock2.h>
#include <windows.h>

换成

#include <windows.h>
#include <winsock2.h>
看看


SOCKADDR_STORAGE
Client: Included in Windows XP.
Server: Included in Windows Server 2003.
Header: Declared in Winsock2.h.

谢谢楼上,交换位置不好使
请问SOCKADDR_STORAGE和sockaddr有什么区别？能否用后者替换前者

[mr.zhoux]

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 structure.



msn上面这么解释的,能替换:~) e 文不好,你看看吧...

[lllxy]

struct sockaddr_storage {
u_char sa_len;
u_char sa_family;
u_char padding[128];
};

如果出现这个问题，你把这个结构体手动加入到对应的文件中。

楼主所使用的winsock2.h不是最新的？

VS2005中有这个结构的定义。
