请问connect()failed:10060什么意思？

我写了个网络通信的程序，有时候能运行出来，但是有时候运行不了，或者运行着的时候就蹦出个对话框提示connect()failed:10060，我就纳闷了！难道是通信有问题？

连接超时的话，检查一下网络是连接问题，还是防火墙问题还是什么问题？

找来的，当然可以应用于WSAGetLastError()



 1  

 2 /* 

 3 利用FormatMessage函数得到错误代码的文本显示。而错误代号则可由GetLastError()获得。（_WINDOWS）

 4 */ 

 5  

 6     DWORD nErrorNo = GetLastError ( ); // 得到错误代码

 7     LPSTR lpBuffer;    

 8     FormatMessage ( FORMAT_MESSAGE_ALLOCATE_BUFFER  | 

 9          FORMAT_MESSAGE_IGNORE_INSERTS  | 

10         FORMAT_MESSAGE_FROM_SYSTEM,

11         NULL,

12         nErrorNo, // 此乃错误代码，通常在程序中可由 GetLastError()得之

13         LANG_NEUTRAL,

14         (LPTSTR) & lpBuffer,

15          0 ,

16         NULL );

17     CString strErrorCause  =  lpBuffer  ?  _T(lpBuffer) : _T( " Sorry, cannot find this error info. " );

18     UpdateData (FALSE);

19  

20      //  Free the buffer. 

21      LocalFree (lpBuffer);

WSAGetLastError对号入座即可。
#define WSAETIMEDOUT (WSABASEERR+60)
如果需要文字解释，使用FormatMessage把错误码转换为系统错误描述信息出来即可。

C/C++ code

可以举个例子吗？
