[Pyrex] Inheritance for extension types

[q q]

Hello,
I'm a Pyrex newbie and i am trying to do the
following:
I have two files: a definition file and a
implementation file
The definition file contains the following code:
cdef class A:
   cdef int length

cdef class B(A):
   cdef int width

The implementation file contains the following code:
cdef class A:
   def __new__(self,int length):
      self.length=length

cdef class B(A):
   def __new__(self,int length, int width):
       A.__new__(self,length)
       self.width=width

This does not compile and i get a traceback from
Python.
The documentation does not give any info about how
transmit parameters to the parent class

Thank you for helping

Alain
