Subject: [TUHS] Excise process from a pipe
Date: Thu, 10 Jul 2014 12:12:01 -0400 (EDT) [thread overview]
Message-ID: <20140710161201.6878718C09B@mercury.lcs.mit.edu> (raw)
PS: I see I have over-generalized the problem. Doug's original message say "a
process could excise itself from a pipeline". So presumably the initiation
would come from process2 itself, and it would know when it had no
internally-buffered data.
So now we're back to the issue of 'either we need a system call to merge two
pipes into one, or the process has to hang around and turn itself into a cat'.
