use win32 COM in python

[Lin Jingxian]

hi,
  I have a C++ implemented COM server that give out a method like: int
read(unsigned char* buf, int lenth), How can I use this method from python?
what is the signature?
or anyone can tell me how should I design the COM interface so I can use
python to read a chunk of bytes from a C++ implemented COM server.

thanks.
