Exactly. And that could well be the wrong type of syscall to use. For
example, how do you implement traditional Unix IPC message queues on
Windows..? There are several options (from WM_USER messages to DDE)
and some will be simply a bad choice under certain circumstances.

Right. My take is however, with my software developer hat on, that you
should not get to that stage if you know what the heck you're doing in
the first place on that o/s. That's the point I'm trying to make. You
cannot take your Unix savvy and apply just like that to Windows. Or
vice versa. Yet, this is exactly what is being done (at sysadmin and
developer and dba levels) and is the prime reason why the perception
persists that "this o/s is slow and bad and sucks".

Is it frustrating to go from one o/s to another? Hell yes. But
recognise the fact that the new o/s is *different*.

The old story of emptying your cup of coffee before pouring tea into
it, as that's the only way you can really taste and enjoy the tea.
