Re: Waiting on data from driver

Sure, but your API had better be well documented, which in my book is full
documentation of the driver. The point is that the app deve needs
documentation of everything that they may need to effectively use the
driver, otherwise the driver isn't useful. Whether you choose to use the
standard stream interface, or a more friendly shim API doesn't matter -
providing docs on usage is important. Simply giving a header file and
saying "good luck" isn't appreciated.
