Safearray question

[bumperdoc at gmail.com]

Hi
I'm using win32com.client to dispatch a COM server....one of the
interface methods has the below parameter:

..., [in, out] SAFEARRAY(BYTE) *Buffer, ...

This method goes and queries something and puts it in this buffer...how
can I use this method in Python?  What type of variable needs to be
passed in when calling this method?
Thanks in advance.
