Couple of questions about namedpipes

General Usage
1

Hey All :slight_smile:

I’m trying to communicate from Julia to Python via namedpipes. I open a pipe in julia

julia> s = listen("\\\\.\\pipe\\p123")
Sockets.PipeServer(Base.Libc.WindowsRawSocket(0x0000000000000708) active)
julia> c = accept(s)
Base.PipeEndpoint(Base.Libc.WindowsRawSocket(0x00000000000006ec) open, 0 bytes waiting)
julia> c
Base.PipeEndpoint(Base.Libc.WindowsRawSocket(0x00000000000006ec) open, 0 bytes waiting)

Connect from python and close the pipe:

>>> f = open("\\\\.\\pipe\\p123")
>>> f.close()

After that I check whether the pipe is still open. That’s true and I write to it.

julia> isopen(c)

julia> write(c,"Hallo Welt")
ERROR: IOError: write: broken pipe (EPIPE)
Stacktrace:

julia> isopen(c)
true

I get an error as expected but why is the pipe still open?
