I'm looking to convert a synchronous Read to asynchronous with the
IOUSBCompletionAction callback.
>From the documentation, I've not been able to figure out the data path.
http://developer1.apple.com/documentation/Darwin/Reference/IOKit/USB/CompositePage.html
I'm expecting to pass in a "this" reference in order to save the data
within the callback Which is the correct pointer: target or
parameter?
What do I set the parameter (or is it target?) value to when
initializing a IOUSBCompletion?
What do I dereference the parameter (or target) value to in order to
get at the USB data?
A data flow example would be greatly appreciated.
Thanks,
Dean Goodmanson
