Windows XP 中是否有 inet_ntop / InetNtop 的替代方案？

Question

I'm trying to compile beej's guide to network programming examples, but Windows XP doesn't have such a function. I'm using mingw, if it makes any difference.

Answer 1

From the WinSock layer:

• WSAAddressToString (ntop)
• WSAStringToAddress (pton)

Answer 2

If you're only dealing with IPv4 addresses, you can use inet_ntoa . It's available on Windows 2000 or later. Otherwise you'll have to either require Vista and later, or write your own inet_ntop function.

You could also look at boost - the boost::asio has an inet_ntop implementation that works in Windows: boost::asio::detail::socket_ops::inet_ntop . You can see the source code here .

Answer 3

There is also inet_ntop function in POSIX compliant libc for Windows (PlibC) library that was created for porting POSIX applications to Windows. There is no notes about it in online documentation , but it exists in file inet_ntop.c at least since 2008 (according to file date).

const char * inet_ntop(int af, const void *src, char *dst, size_t size)

Answer 4

you can use winsocket with mingw-64 on windows 7

#include <winsock2.h>
#include <windows.h>
#include <ws2tcpip.h>

linkwith

gcc showip.c -lws2_32

Target: x86_64-w64-mingw32 Thread model: win32 gcc version 6.3.0 (GCC)

Answer 5

You might want to use something Jeroen Massar provided here , excerpt from his post follows:

const char *inet_ntop(int af, const void *src, char *dst, socklen_t cnt)
{
    if (af == AF_INET)
    {
        struct sockaddr_in in;
        memset(&in, 0, sizeof(in));
        in.sin_family = AF_INET;
        memcpy(&in.sin_addr, src, sizeof(struct in_addr));
        getnameinfo((struct sockaddr *)&in, sizeof(struct
            sockaddr_in), dst, cnt, NULL, 0, NI_NUMERICHOST);
        return dst;
    }
    else if (af == AF_INET6)
    {
        struct sockaddr_in6 in;
        memset(&in, 0, sizeof(in));
        in.sin6_family = AF_INET6;
        memcpy(&in.sin6_addr, src, sizeof(struct in_addr6));
        getnameinfo((struct sockaddr *)&in, sizeof(struct
            sockaddr_in6), dst, cnt, NULL, 0, NI_NUMERICHOST);
        return dst;
    }
    return NULL;
}
