#99 Feature request: ReadFileEx/WriteFileEx

[Jan-Philip Gehrcke]

I was just happily working myself into the pywin32 package unitl I found that the main functions I need are not available:
ReadFileEx/WriteFileEx

I'll stick to a ctypes-based method for now. However, future users might be happy to see these functions.

I had looked at these a while back, and the reason I didn't wrap them is the lack of a way to pass a python function to the callback. Most of these types of callbacks have an extra "context" arg - a void pointer that we can use for that purpose. However, this one doesn't provide for a context. Maybe we could associate the callback with the file handle or the Overlapped object.
