IIRC, unlike unix, win32 distinguishes between POSIX file descriptors (int) and sockets (SOCKET). This goes all the way back to win3.1 winsock and the consequence is that you can't use recv() to read from files (you will get a WSAENOTSOCK error) and you can't use read() to read from sockets (you will get an EBADF error). Also, you can't fdopen() sockets for the same reason (sockets aren't file descriptors in win32). http://msdn.microsoft.com/en-us/library/ms740121(VS.85).aspx http://msdn.microsoft.com/en-us/library/wyssk1bs(VS.80).aspx This is for the win32 API--I have no idea with .NET.
