|Hello,
|
|I'm doing some programming with NT and sockets.  I was under the impression

|that in NT, sockets were implemented as HANDLES.  This would make it
possible
|to use sockets on functions like ReadFile/WriteFile.  However, when I try
to
|insert a SOCKET in place of the HANDLE in the function call, Visual C++
|(NT version) refuses to accept this.  Is it possible to use sockets and
|HANDLES interchangeably in any of the NT file calls?

cast the SOCKET returned from socket() to a HANDLE when passing to
ReadFile() etc.  that should do the trick.

one caveat: NT sockets are opened as overlapped handles, so you need to
specify the LPOVERLAPPED handle on ReadFile() in order to successfully use
that routine with a socket handle.

|I'm in the process of doing some design work for a gateway program,
|which should on one side be based on WINSOCK.  The gateway should be
|able to handle between 100 and 300 TCP connections concurrently.
|
|I've browsed through some doc about the WIN32 API, but didn't find
|anything about WINSOCK there.  I've some questions...
|
|1) Is there a limit of sockets available to one task? Can this limit
|   be configured?

no static limit, it just depends on how much physical memory your machine
has.

|2) From what I've seen a SO_REUSEADDR socket option is supported.
|   Can two tasks use the same listener port, then? How are incoming
|   connect requests multiplexed between those tasks? Does always the
|   first one in the queue with enough available backlog in listen()
|   get it?

both tasks can listen() on sockets bound to the same port, but there are no
guarantees as to which one will get incoming connections.  because of this,
it is usually better to have a single listening socket which passes accepted
sockets off to other threads or processes.  that way, you have control over
where each socket goes and can implement any necessary round-robining
yourself.

Is there a non-commercial NFS-client for Windows ?

Or paraphrased: if I have a Winsock running, how do I make my Windows-tasks
(e.g. filemgr) see a Unix filesystem ?

Where did you DL it?   I forgot to include bwcc.dll in the first archive
file.You can get the complete archive at sparky.umd.edu in /pub/winsock.
