Hello,

I need to setup communication between two Ocaml processes on Windows.
I think that using the named pipe of Windows is the good method to do this task.

But I can't find any module for Ocaml who allow using the system call of Windows.

I have already find this module https://opam.ocaml.org/packages/named-pipe/, but it use C,
and I would like to avoid depending on another langage than Ocaml or software like Cygwin.

Although I'm one of the authors of that particular library I now prefer to use this other library instead:

https://github.com/fdopen/uwt

https://opam.ocaml.org/packages/uwt/

where "Uwt.Pipe" is a Unix domain socket on Unix and a named pipe on Windows. I'm very happy with "uwt" -- it seems to be very stable and reliable, despite the relatively low version number.

Personally I don't want my final executables to depend on the cygwin.dll but I don't mind if my development environment uses cygwin for the Unix utilities like "make", "vi" etc. I usually install OCaml one Windows using this installer:

http://fdopen.github.io/opam-repository-mingw/installation/

-- this installs everything you need (including Cygwin). I then `opam install` my dependencies and `make`, like I can on Unix. My resulting .exe files are independent of cygwin.dll and I ship them as-is.

Hope this helps a little,

Dave

Does anybody know a way to use named pipe of Windows in Ocaml ?

Thank you in advance for your answer !

Ps : Sorry if it's the wrong mailing list to ask, it's the first time I use one.
