Setsockopt()返回错误号10042

Question

所以我开始使用SCTP，并编写了SCTP服务器应用程序的基础知识(我打算修改它以使其成为点对点应用程序)。代码是不完整的，但我编译并运行它来测试套接字选项和第一个setsockopt返回错误10042(协议不支持)。我已经确定，这是setsockopt()的第一次调用，返回一个错误。下面是不完整的代码:

#include "stdafx.h"
#include <iostream>
#include <iostream>
#include <string.h>
#include <stdlib.h>

#define UNICODE
#endif

#include <WinSock2.h>
#include <WS2tcpip.h>
#include <WS2spi.h>
#include <ws2sctp.h>

    int iResult;

    u_long imode = 1;
    bool connected = false;
    char *optval = (char*)&optv;

    memset(&servAddr,0,sizeof(servAddr));

    iResult = WSAStartup(MAKEWORD(2, 2), &wsaData);
    if (iResult != NO_ERROR) {
        wprintf(L"WSAStartup function failed with error: %dn", iResult);
        return 1;
    }


    SOCKET servSock = socket(AF_INET6,SOCK_STREAM,IPPROTO_SCTP);
    if(servSock==INVALID_SOCKET){

        return 1;
    }

    evnts.sctp_data_io_event = 1;

如果它与python包nameko/kombu/amqp有关，则此处报告2.1.4版本的问题。

Temporary soln:回滚到2.1.3版本，直到它被修复。

好了，伙计们，我修复了它(现在 lol)。我所做的是用IPPROTO_SCTP代替IPPROTO_IPV6，它似乎有效。
