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）。代码不完整但我编译并运行它来测试套接字选项，第一个setsockopt返回错误10042（不支持协议）。我已经确定这是第一次调用setsockopt（）返回错误。所以这是不完整的代码：

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

#define UNICODE

Answer 1

如果它与 python包nameko / kombu / amqp 相关，则会在此处报告Issue with 2.1.4 version。

临时溶解：将版本回滚到2.1.3，直到它被修复。

Answer 2

好的伙计们，我修好了（现在 lol）。我所做的是将IPPROTO_IPV6替换为IPPROTO_SCTP，它似乎有效。

Setsockopt（）返回错误号10042
