Re: [RFC] cleaner FD_TYPE_XXX implementation

[Mike McCormack]

Hi Martin,

Sorry, i should have been a little more clear: if there is a
overlapped console, the code in ReadFile (ie. the implemention) will
ignore the fact that it is a console, and treat it as a standard
overlapped file. In other words, ReadFile should check if the fd is a
console fd first, then check if it has the overlapped flag.

What you're trying to do is good, and my complaint is just a quibble
since the console code doesn't support overlapped operations now
anyway :-]

[RFC] cleaner FD_TYPE_XXX implementation

[Martin Wilck]

Yeah, if there is such a thing a s an overlapped console in the future,
the ReadFile() code must make a more fine-grained distinction. Unlike
before, though, ReadFile() will now know that it is an overlapped console
rather than simply an "overlapped" fd. Similar arguments may hold for
other IO objects, too.

Thanks for commenting,
Martin
