Yep, and before getting blocked, read() increments the counter as well, that's
why we don't have a xnpipe_realease() called as a result of close().
So everything is correct.
Fine.
Hi,
My application consists of a real time module and a non-realtime user
mode program. They communicate through several pipes.
The user mode program creates a thread (pthread) that opens a pipe and
blocks in a read call, waiting for data. Under certain conditions, the
user mode program must do
As a conclusion, the behaviour that you observed with Xenomai
pipes seems consistent with that of Linux' named pipes, except
that in Linux read() returns 0, and not an error code as you
observed with Xenomai.
The read() call does *not* return when you close the *same* file handle
