服务器未检测到winsock中的客户端 [英] server not detecting clients in winsock

问题描述

netwrok编程的新手我创建了一个服务器端应用程序，因为客户端驻留在微控制器上。我遇到的问题是我无法接收任何传入的连接

Am newbie to netwrok programming i have created a server side application since client side resides a microcontroller. The problem am encountering is that i cannot be able to receive any incoming connections

int main()
{
	char ans;
	printf("Starting up server........\n");

	// our masterSocket(socket that listens for connections)
	SOCKET sock;
	// for our thread
	DWORD thread;
	WSADATA wsaData;
	sockaddr_in server;
	// start winsock
	int ret = WSAStartup(0x101, &wsaData); // use highest version of winsock avalible
	if (ret != 0)
	{
		return 0;
	}
	// fill in winsock struct ... 
	server.sin_family = AF_INET;
	server.sin_addr.s_addr = INADDR_ANY;
	server.sin_port = htons(39950); 

	sock = socket(AF_INET, SOCK_STREAM, 0);
	if (sock == INVALID_SOCKET)
	{
		return 0;
	}

	// bind our socket to a port(port 123) 
	if (bind(sock, (sockaddr*)&server, sizeof(server)) != 0)
	{
		return 0;
	}

	// listen for a connection  
	if (listen(sock, 5) != 0)
	{
		return 0;
	}

	SOCKET client;
	sockaddr_in from;
	int fromlen = sizeof(from);
	// loop forever 
	while (true)
	{
		//printf("check up!!!!!!"); ........ prints this one
		// accept connections
		client = accept(sock, (struct sockaddr*)&from, &fromlen);
		printf("Client connected\r\n"); ...... cannot print this one
		// create our recv_cmds thread and parse client socket as a parameter
		CreateThread(NULL, 0, receive_cmds, (LPVOID)client, 0, &thread);
	}
	// shutdown winsock
	closesocket(sock);
	WSACleanup();
	// exit
	return 0;
}

推荐答案

你试过写一个客户端 然后连接到您的服务器??

Did you try to write a client and then connect to your server??
