无法在 Windows 上创建套接字 [英] Can't create socket on Windows

问题描述

我有一个很尴尬的问题.以下代码不会在 Windows 上创建套接字；它失败并显示错误消息.谁能简要解释一下为什么会这样?我非常困惑和沮丧，如此简单的事情失败了.谢谢.

I have quite an embarrassing problem. The following code simply will not create a socket on Windows; it fails and displays the error message. Could anyone briefly explain why this might be? I'm incredibly confused and frustrated that something so simple is failing. Thank you.

int sock;
if( (sock = socket(AF_INET, SOCK_STREAM, 0)) < 0 )
{
    printf("error opening socket");
}

另外，打印出 strerror(errno) 只是显示没有错误".

Also, printing out strerror(errno) simply shows "No error".

推荐答案

您需要调用 WSAStartup() 在任何其他套接字函数在 Windows 上工作之前(并且您应该调用 WSACleanup() 完成后.

You need to call WSAStartup() before any other socket functions will work on Windows (and you're supposed to call WSACleanup() when you're done).
