You're talking about Linux FIFOs, which don't make *any* sense on Cygwin, and I'm talking about Cygwin FIFOs which don't make *any* sense on Linux or, FWIW, a remote NFS fileystem. So if you want Cygwin to be able to create FIFOs on a remote NFS, which Cygwin won't be able to use, great. I don't see any sense in that, but, as usual, https://cygwin.com/acronyms/#PTC Corinna -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
