请教一下, 我的accept怎么不阻塞呢?

[zheyimiao]

以前用的时候都会阻塞的,突然就不阻塞了,代码如下:

#include "stdafx.h"
#include <WinSock2.h>

#pragma comment(lib, "ws2_32.lib")

BOOL InitSocket()
{
	WORD word;
	WSAData wsaData;
	word = MAKEWORD(2, 2);
	SecureZeroMemory(&wsaData, sizeof(WSAData));

	if (WSAStartup(word, &wsaData))
	{
		return FALSE;
	}

	return TRUE;
}

int _tmain(int argc, _TCHAR* argv[])
{
	SOCKET listensock, acceptsock;
	sockaddr_in sockAddr = {0};
	sockaddr_in sockClient;
	int iClientCount = 0;
	int iLength = 0;

	SecureZeroMemory(&sockClient, sizeof(sockaddr_in));
	listensock = INVALID_SOCKET;
	acceptsock = INVALID_SOCKET;

	if (!InitSocket())
	{
		printf("InitSocket Failed\n");
		goto exit;
	}

	listensock = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);

	if (listensock < 0)
	{
		printf("socket Failed. Error code : %d\n", WSAGetLastError());
		goto exit;
	}

	sockAddr.sin_family = AF_INET;
	sockAddr.sin_port = htons(10001);
	sockAddr.sin_addr.s_addr = htonl(INADDR_ANY);
	
	if (bind(listensock, (sockaddr *)&sockAddr, sizeof(sockaddr)))
	{
		printf("bind Failed. Error code : %d\n", WSAGetLastError());
		goto exit;
	}

	if (listen(listensock, 5))
	{
		printf("listen Failed. Error code : %d\n", WSAGetLastError());
		goto exit;
	}

	while (true)
	{
	    acceptsock = accept(listensock, (sockaddr*)&sockClient, &iLength);
	    printf("%d\n", ++iClientCount);
	}

exit:
	WSACleanup();

	if (INVALID_SOCKET != listensock)
	{
		closesocket(listensock);
		listensock = INVALID_SOCKET;
	}

	if (INVALID_SOCKET != acceptsock)
	{
		closesocket(acceptsock);
		acceptsock = INVALID_SOCKET;
	}

	system("Pause");
	return 0;

看起来没问题啊，你这个只是accept而已啊。一直在循环等待。没有send,recv收发数据。

没细看你的代码，你仔细查一下是不是goto的原因。

我调试的时候,到达accept语句,没有阻塞就执行下一句了.所以打出的客户信息一直增加.

[wangxipu]

int iLength = sizeof(sockaddr_in);

[zheyimiao]

You got it! 谢了

int iLength = sizeof(sockaddr_in);
