Date: Sun 11-Sep-1990 22:39:20 From: Unknown Subject: Named pipes and Next I am writing a utility that uses named pipes (created by 'mknod p name'). It works fine on suns, decs and even IBM aix. Only today I found out the NeXT (I'm not sure about Mach in general) does not support them, and I am looking for a simple alternative. Is there a *simple* way of creating an effective pipe between two independent processes? The Speaker Listener mechanism sounds about right, but I'd rather not go into objective C. Any ideas?

If you want to be Mach or NeXT-specific, you could use Mach ports and the name-server; unless you use NXStreams though you have to invest a little learning about "Mach Interface Generator" and details of mach ports (which I myself still haven't done =8) ). Since this is comp.os.mach + comp.sys.next I guess you're not worried about portability off of a NeXT. Check allocate_port() and NXOpenPort() in the manuals. The nameserver is under netname_check_in() and netname_look_up(). Article 7713 of comp.sys.next: >From: stuart@previous.ADS.COM (Stuart Crawford)
