What makes you think so?

AFAICS, the man page applies for posix_memalign, aligned_alloc, memalign,
valloc and pvalloc.

In case behavior differs between the functions, this is stated explicitly, e.g.
in the "RETURN VALUE" section.

The "ERRORS" setion does not differentiate, hence it should apply to all the
functions above, including aligned_alloc.

Do I miss anything?
