Re: [alsa-devel] Third time: Unlink PCM resource ?

OK, I see the problem now, too. In practice, you can get a file descriptor from poll descriptor, but this doesn't cover all underlying fds. A new API function or an additional SND_PCM_* flag for snd_pcm_open() would be needed, indeed.

In the latter case, it must be easy -- just pass O_CLOEXEC flag to open() call...

That handles the close on exec well, but we are talking about forks here. There is not necessarily an exec involved in the child process.
