That doesn't mean they can't use the same basic model though. With IOCP when a read operation unblocks the data is already in the buffer while with the other methods a read operation has to be done. Wrap that bit in the IO subsystem.
To do it most efficiently, both read and write buffers are needed, since there should be at least two concurrent asynchronous reads and writes. I don't think that is a major problem though --- buffers can be used in almost all.

What remains an issue in my mind is how far to take this. Socket and file classes for each platform at least... what else?
In addition to the asynchronous/non-blocking socket system, it would be useful to provide a blocking socket system. This could be have a streambuf interface. -- Jeremy Maitin-Shepard
