Only if you can clearly communicate why the linux API doesn't work. I'm
not convinced that this is not just a misconception on your part.
Or to put it another way -- cygwin is rather careful when it comes to
pipes to make sure that all of these uses work correctly and
interoperate with with windows:
C:\>dir | less
C:\>ls | less
C:\>dir | \windows\system32\more.com
C:\>ls | \windows\system32\more.com
$ cmd /c dir | les
$ ls | less
$ cmd /c dir | /cygdrive/c/windows/system32/more.com
$ cmd /c dir | /cygdrive/c/windows/system32/more.com
(ie all 8 combinations of pipe-created-by:{win,cygwin},
source:{win,cygwin}, sink:{win,cygwin} )
So, the big question is: what does brltty do with pipes that is
different to the above?
I know there are certain potential problems with non-blocking I/O on
pipes on cygwin, but they are limited to quite specific cases (rsync
is the main one that trips over this).
