I have no objection, but for what it’s worth, there could be code out there that uses __mq_oshandle() simply because it’s been around for a while and has been the only way to use poll(), select(), or kevent() with an mqueue ever since an mqd_t changed from an integer to a pointer.

In our case, we have a half-dozen or so source files that reference __mq_oshandle(), but we don’t mind changing them if it’s better in the long run.  I’m merely pointing out that it’s incompatible with previous FreeBSD versions.

Thanks,
