Thanks for the patch!

I didn't see aio_buf in https://pubs.opengroup.org/onlinepubs/9799919799/basedefs/aio.h.html. Can you triple check?

[nickdesaulniers]

Not a function in https://pubs.opengroup.org/onlinepubs/9799919799/basedefs/aio.h.html. Looks like a member of struct aiocb (we don't need to document those). It's possible perhaps it was deprecated/removed from POSIX though. Can you check?
