Hi!

I am trying to build a simple concurrent TCP server using gnuwin32 in a
Win95 environment. In the Unix way, the server listen to a port, accept
it and fork a child process to handle the accepted socket. I tried the
same thing in gnuwin32. However, I alwasy get a error when a error
"descriptor is a file, not a socket" whenI tried to use this socket in
the child process(select,recv, etc).

I would like to know whether passing a child process inherit the socket
handle from the parent in gnuwin32/Win95.　

Thanks!

Thanks! I fingure out this from your web site later. Anyway, signals
don't work very well in Win95 too. Later I swith to use the Win32 thread
instead the old unix way fork/exec. It works. Kinda! It stops once a
while for no reason. It seems to me the Berkeley socket in GNU-Win32 is
not really thread-safe. So I switch to winsock. It works but just that
Unix like anymore.

Socket() call on windows95 creates a non-inherittable socket! Download patched cygwin.dll from my web page - it handles this bug of Win95.
