newbie help

How about describing what your program is supposed to /do/ instead of
posting C code?  What are the "buffers" for?  This group might be more
helpful if you did that.

If you really do need this sort of random-access character buffer, you
have a couple of options. Python strings aren't mutable, so they won't
work.  To start with, lists of characters would suffice, or mmap (look
it up in the global module index)
