When we used PVCS, many many moons ago, in a mixed windows/SCO Unix
environment, all sources were stored on the unix box. We got a huge
software package to maintain, appr. 500K lines of 'C'. What we wanted
was to Set a standard header with PVCS labels in any file we touched. So
we had a script dealing with all files that got saved. This script ran
on Unix, in an infinite loop. It was just sitting there, waiting for a
new full path filename appearing, to handle/process this file, if
necessary. Guess what, the PVCS post-check-in trigger wrote the
file-name to a unix pipe, even on Windows. We created the named pipe for
this in a directory that was shared through samba. To prevent early
EOF's happening, we had another script, while : ; do; sleep 3600 ; done
><thepipe> running, keeping it open as long as we wanted.
I don't have a windoes Oracle client at hand here (lucky me ;-) ), but
I'm getting curious whether this could make you writing to a
(Unix/Linux) pipe on Windows!
