I am obviously aware of the fact that FPC has an IPC unit which uses a
temporary
file, although I have always assumed that that was more to support
targets like
DOS that had absolutely no concept of pipes or sockets. But perhaps it
really is
the safest choice in all cases.
FWIW: DOS does have and has had pipes... otherwise things like DIR |

Yes, I do. And I'm obviously aware that there are plenty of addons that
graft named pipes (and mailslots etc.) onto DOS. However I always think
of named pipes, threads etc. as being primarily OS/2 v1 innovations,
although some might have been introduced by the obscure Microsoft OS
usually referred to as "European MS-DOS v4.0".
