[PATCH] mq_open() and close_on_exec
From: Chris Wright <chrisw@osdl.org>
SUSv3 doesn't seem to specify one way or the other. I don't have the POSIX
specs, and the old docs I have suggest that mq_open() creates an object
which is to be closed upon exec.
Jakub said:
I think it is valid and required:
http://www.opengroup.org/onlinepubs/007904975/functions/exec.html
All open message queue descriptors in the calling process shall be
closed, as described in mq_close()
I'll add a new test for this into glibc testsuite.
