Error on linux

I'm using ctypes v 0.9.1 on linux for the first time.

Then I try to use create_unicode_buffer(), I receive this error:

File "/usr/lib/python2.3/site-packages/ctypes/__init__.py", line 74, in 
create_unicode_buffer
    buftype = c_wchar * init
NameError: global name 'c_wchar' is not defined

What can I do?

Thanks,
Michele Petrazzo
