You REALLY need to read the docs provided in the Win32\Help folder; look
for the file named PythonWin32Extensions.hlp.  Use the Index, Find feature 
to locate the ReadFile function.

I considered explaining the details here, but there are two very different
cases, so you should just RTM yourself on this one.

BTW Many people don't even realize that help file is there...
