'inet_pton'：未找到标识符 [英] 'inet_pton': identifier not found

问题描述

我试图在我的程序中包括以下代码，但会出现错误（'inet_pton'：identifier not found）。

  // IPv4：
 
 struct sockaddr_in ip4addr; 
 int s; 
 
 ip4addr.sin_family = AF_INET; 
 ip4addr.sin_port = htons（3490）; 
 inet_pton（AF_INET，10.0.0.1，& ip4addr.sin_addr）; 
 
 s = socket（PF_INET，SOCK_STREAM，0）; 
 bind（s，（struct sockaddr *）& ip4addr，sizeof ip4addr）; 
  

输出

 错误C3861：'inet_pton'：未找到标识符
  

  #include< stdio.h> 
 #include< stdlib.h> 
 #includeudpDefine.h
 #include< windows.h> 
  

任何帮助可能会错过一些标题或lib。

解决方案

函数

  int inet_pton（int af，const char * src ，void * dst）; 
  

在头文件中声明：

  #include< arpa / inet.h> 
 

如果这是Windows（Vista或更高版本），Winsock类似于此ANSI版本：


$ b）;


请尝试 #include< Ws2tcpip.h>
add Ws2_32.lib

I'm trying to include the following code in my program but the error ('inet_pton': identifier not found) will appeared.

// IPv4:

struct sockaddr_in ip4addr;
int s;

ip4addr.sin_family = AF_INET;
ip4addr.sin_port = htons(3490);
inet_pton(AF_INET, "10.0.0.1", &ip4addr.sin_addr);

s = socket(PF_INET, SOCK_STREAM, 0);
bind(s, (struct sockaddr*)&ip4addr, sizeof ip4addr);

Output

 error C3861: 'inet_pton': identifier not found

the including header

 #include <stdio.h>
 #include <stdlib.h>
 #include "udpDefine.h"
 #include <windows.h>

any helping may be missed some headers or lib.

解决方案

the function

int inet_pton(int af, const char *src, void *dst);

is declared in header file:

#include <arpa/inet.h>

if this is Windows (Vista or later) there is Winsock analog to this ANSI version:

INT WSAAPI InetPton(
  _In_   INT  Family,
  _In_   PCTSTR pszAddrString,
  _Out_  PVOID pAddrBuf
);

try #include <Ws2tcpip.h> add Ws2_32.lib
