[Pyrex] cdef methods still unclear

[Helmut Jarausch]

Sorry, bothering you again,
but the documentation is short!

I'd like to have a cdef function within
an extension type which is only called
by other Pyrex functions.
But I can't even define it.

What's wrong with

cdef class Document:
  cdef char* buffer
  cdef int   buffer_len

  cdef char* iso1_to_utf(char* in):
# ------------------ Expected ')'  <<<<< ERROR
    return in


Furthermore, would it be possible for this
iso1_to_utf to access self.buffer ?

Many thanks for a hint,
