The C APIs haven't quite settled down yet, but I'd like to convince
you that you needn't wait. For all bytes input, you should use the
(new) buffer API,i. e. PyObject_GetBuffer() and
PyObject_ReleaseBuffer() (grep for usage examples if they aren't
sufficiently documented in the docs or in PEP 3118). For stuff that
returns bytes, you can either use PyBytes_FromStringAndSize() -- which
is the 3.0a1 recommended best practice (returning a mutable bytes
object) or PyString_FromStringAndSize() -- which will be the 3.0a2 way
of returning an immutable bytes object). Since they have the same
signature there's very little to worry about having to change this
around later.
