[Boost-users] [boost.asio / asio] leaving descriptor open in posix::stream_descriptor
Daniel Mierswa
is it possible to avoid closing the descriptor when the destructor
of posix::{basic_,}stream_descriptor is called?
I guess I have to roll my own service or something else but I don't know
where to start, I'm also sending this to the boost mailing list.

If you still don't like it, that's ok: that's why I'm boss. I simply know better than you do.

Unfortunately it isn't (stream_descriptor always owns the file descriptor).

I also would like to see a stream_descriptor which doesn't own the file
descriptor as right now you can't share ownership with other objects
(that's why I had to add a release() method to the handle class in the
latest Boost.Process draft as ownership must be passed from handle to
stream_descriptor).

I guess one could ::dup/::fcntl it to create a shared file descriptor
and give that to asio. What do you think of that?

Sounds good to me and should work. :)
