Not much details though. Oh well.



The code in Research Unix V8, V9, and V10 is available. Alcaltel-Lucent made them public a couple months ago[0]. Here are the relevant URLs and file paths within the archives. I already had them on my hard drive and it was easy to grep them. I removed a few columns from the output of tar.

Edited to fix formatting.


Oh, nice! But I can't find the right man page.


V8 doesn't have a /dev/tcp man page but the interface is documented at /usr/include/sys/inet/tcp_user.h[0].

Here are the commands I used to identify the right file.

find . -type f -print0 | xargs -0 grep -I "/dev/tcp" | less

Edited to add the command sequence for the historical record.

Edited again to fix wording of the first sentence.


That's not very documented. How would someone use this?


V10 has a man page. Extract v10src.tar and look at man/adm/man4/tcp.4.


Okay, this I took a quick look at it, and this seems way to awkward to use from a shell script. It's pretty much C only. I guess Plan 9 does better.


thanks!
