Dear Don,
I went back to my archives....
This is the situation:
1. the code in CVS had always
int trigger[2];
2. I took the version 4.5.1 from the tar ball dated 2009-02-02 and I did the
change
SOCKET int trigger[2]; to make it work
3. then I recently took the Aolserver code from CVS Head and forgot to make
the above change and so I started to observe problems in the networking
code....
4. re-inserted the change and everything seems to work... but I will test it
and very deeply.....
5. I have to disagree with your statement
" A Unix pipe is just a pair of file descriptors, and a file descriptor in
Unix is just an integer."
If I look at the code base (and please do the same with me)... check
nscp/nscp.c
nsd/binder.c, fd.c, listen.c, sock.c, tclfile.c, tclhttp.c, urlopen.c
nsext/nsext.c
nspd/nspd.c
nsproxy/nsproxylib.c
nssock/nssock.c
nssl/nssl.c
Well not always "sockets" are declared/defines as SOCKET as they should be
(and this I am afraid also in Unix)
This is a problem of proper data type selection and usage, it is mostly a
consistency problem.
I would humbly suggest that one of the code maintainers takes a walk on the
code base and makes sure that everywhere we need a "socket" we have a real
SOCKET socket and not an int socket.
The code will be more consistent and more portable to Windows.
Ciao,
Maurizio
PS: the attached text file shows where the keyword SOCKET is currently
used...

is this an int when it was a SOCKET (any justification????)
A Unix pipe is just a pair of file descriptors, and a file descriptor in
Unix is just an integer.
Windows pipes are implemented differently, of course, and the semantics
aren't exactly the same, either.
Can you tell from CVS who put this code in?
I'm sure it was done from ignorance of Windows vs. Unix differences
regarding pipes, not intentionally.

Not in this case, no, that's perfectly reasonable Unix code.
