[asio-users] Problem with windows::stream_handle

[Zachary T. <div...@gm...>]

I am using stream_handle and constantly calling async_write with a set
of buffers whose sizes total up to N.  Instead of doing what I would
expect, which would be to always append subsequent writes at the end
of previous writes, it just keeps overwriting the same data
constantly, and never seeks forward at all.   The destination file
remains at a constant size N throughout the entire operation.

Am I doing something wrong?
