奇怪的socket 10038错误

bj_leo_2000 2007-01-09 02:10:03

代码如下：
HANDLE ghController = NULL;
SOCKET gosocket = NULL;
unsigned int __stdcall WorkThread(void*);
int main(int argc, char* argv[])
{
SetConsoleTitle("HHTone服务器"); //设定
printf("服务器启动\r\n");
//初始化socket
WORD lwVersion;
WSADATA wsaData;
int err;

lwVersion = MAKEWORD(2,2);
err = WSAStartup( lwVersion, &wsaData );

if(err != 0)
{
printf("初始化socket库出错:%d\r\n",err);
return 0;
}

if ( LOBYTE( wsaData.wVersion ) != 2 ||
HIBYTE( wsaData.wVersion ) != 2 )
{
printf("socket库版本错误\r\n");
WSACleanup();
return 0;
}
printf("初始化socket库成功\r\n");

printf("创建工作线程\r\n");
_beginthreadex(NULL,0,WorkThread,NULL,0,0);
//创建服务器循环等待
ghController = CreateEvent(NULL, FALSE, FALSE, NULL);
WaitForSingleObject(ghController,INFINITE);
//关闭服务器
if(gosocket != NULL)
closesocket(gosocket);
WSACleanup();
CloseHandle(ghController);
printf("服务器关闭");
return 0;
}
//---------------------------------------------------------------------------
unsigned int __stdcall WorkThread(void*)
{
sockaddr_in loaddr;
int loaddlen = 0;
char lacbuffer[MAX_PACKET_LENGTH]={0}; //接收数据线程
int liRet = 0;
liRet = recvfrom(gosocket,lacbuffer,MAX_PACKET_LENGTH,0,(sockaddr*)&loaddr,&loaddlen);
if(SOCKET_ERROR == liRet)
{
printf("接收数据失败:%d\r\n",GetLastError());
SetEvent(ghController);
return 0 ;
}
return 0;
}

recvfrom时返回错误，错误代码10038

建议楼主单步调试下，看看gosocket是否为先前绑定的值。我也遇到相同的情况，一起解决啊

你的socket一直都是个非法的值，你并没有调用socket()函数穿件socket

这些都没有socket(), bind(), listen(), accept()

C/C++ code

#include "stdafx.h"
#include <winsock2.h>
#include <iostream>
#define PORT_SERVER 6656
#define NUM_CLIENTS 10
int main(int argc, char* a……

这不是网上的一个很广泛转发的代码吗？
监听端口6656 最大连接10
连接时检测SOCKET版本是不是2.0

要接收数据UDP发来的数据,必须先bind到发送端指定的端口
