I found a problem at night, and ia cannot solve it in 5 hours.

I wrote the simple server side on linux (socket, bind, listen.... accept). I connect to this server with a simple Delphi5 client on port 2001 (i tried any other). The "while (not eof(sin))" stops and waits for the forst packet, and so on.
But on windows (with win32 compiler) the same program can read garbage data from sin (text type) and the data is infinity, so i cannot be the end of data.
What is the difference betwwen win32 and linux socket units? What can I do to compile the program perfectly on win32?
// I tried to use file against text sin, sout, and read it by blockread, but it was the same.

Thanx! Best regards

The problem is not in the sockets unit, I think, but in the handling of text files on Win32. I don't know whether there is a simple solution for this.

Yes, maybe it is a text file problem, but I cannot solve it. Did somebody make same program on win32?
Could I try it with recv(), send()? In this case how can i detect the end of communication?

Normally, with select() you can determine whether there is data. with recv() and the MSG_PEEK flag, you can have a peek. This should return 0 if there is no data or the connection was closed.

Ok, fine!

So i can replace procedures that can use textfiles to use recv/send and select(). I am trying now... GOOD!

Thx!

Is select() existing in win32 platform?

It should exist in the winsock unit, I think. It's definitely in winsock.dll
