WinSock Client Error 10053

[Koxin]

I'm working on a piece of networking code I want to use in a multiplayer game. The idea is that the machine that will run the client will sent keyboard status to the server which will reply with the information about the graphical objects the client should draw on its screen. I've studied how sockets work, compiled and tested the examples I found on the internet and all worked fine. The only problem is that I can't run the client code in a loop ( I need to send the keyboard status regularly to the server ). Always when the send() function is run the second time it fails with the error code 10053 -connection closed in host.

this is the code I loop in the client:

while( ! kh.esc )
{
 
   kh.ReadKeys();
   memcpy( buff, &kh, Len );


   if ( ( size = send( mySocket, buff, Len, 0 )) == -1 )
   {
      printf( "Error: %d\n", WSAGetLastError() );
      WSACleanup();
      return -1;
   }

    while ( ((size = recv( mySocket, buf, BUFSIZE, 0 ) ) != 0 ) && ( size != -1 ) )
    {
         text += buf;
         cout << text;             
    }
    
    if (size == -1)
    {
        cout << "Error receiving data" << endl;
    }

    
    Sleep( 100 );
    
}

thanx for help

Error 10053 is Software caused Connection abort.

What's the server code doing?

Where has buf, buff and Len been set? What is text? You are using variables called buff and buf. If these are meant to be different it's not a good idea to have them so similary named for confusion of reading the code. Why are you assuming that buf is 0-byte terminated after the call to recv() when concatenating with text (is text type string?)

The problem was on the server side. I had put the accept() function inside the server loop. The code I posted is kind of messy because it contains both the original code and my modifications - I just used it to study how sockets work.
