Subject: [Xenomai-help] rt_pipe does not support POLLHUP on the Linux side
Date: Fri, 23 Mar 2012 09:35:22 +0100 [thread overview]
Message-ID: <4F6C35CA.8010506@domain.hid> (raw)
Hello,
while playing with rt_pipe, I realized that a select()/poll() function
does not unblock when the rt_pipe is deleted (via rt_pipe_delete) on the
other end. I think this is because the poll callback does not support
POLLHUP:
http://www.rts.uni-hannover.de/xenomai/lxr/source/ksrc/nucleus/pipe.c#1024
Is this by purpose? At least a blocking read() works as expected. It
does unblock and return 0 in that case.
Wolfgang.
