I have no objection, but for what it=E2=80=99s worth, there could be = code out there that uses __mq_oshandle() simply because it=E2=80=99s = 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=E2=80=99t mind changing them if it=E2=80=99s = better in the long run. I=E2=80=99m merely pointing out that it=E2=80=99s= incompatible with previous FreeBSD versions. Thanks, lew
