m_aClientSocket[i]!=INVALID_SOCKET 表示判断当前连接的客户端的socket值是不是非法的，INVALID_SOCKET值应该是-1，表示非法的socket；if(i==MAXClient) return 0L 应该是判断连接是否达到了服务器的最大允许连接数，如果达到了，则不进行连接；...

由于UNIX和Win的socket大同小异,为了方便和大众化,这里先介绍Winsock编程。 socket 网络编程的难点在入门的时候就是对基本函数的了解和使用,由于这些函数的结构往往比較复杂,參数大部分都是结构体,令人难以记忆和理解。 可是一旦我们知道这些函数包含其參数的详细含义
FConnected := FSocket <> INVALID_SOCKET; Event(Self, seConnect); end; end; 和上面说到的Dolisten简直像极了,这里也没有必多说了。我们已经可以向更加简单的第四步进发了。 4. ClientSocket向服务端连接后,WinSock会向服务端发送一个事件,,而上面已经过了事件获取函数:CMSocketMessage ...

If you tried all the above and you still can’t resolve the issue, settingrejectUnauthorizedtofalseallows Node.js to accept and establish connections with servers that have invalid or self-signed SSL certificates, effectively bypassing SSL/TLS certificate validation. ...
