I refreshed my memory re aio.h and found it uses no callback.

Start an asynchronous read operation
Start an asynchronous write operation
Start a list of asynchronous I/O operations
Wait for completion of one or more asynchronous I/O operations
Retrieve the error status of an asynchronous I/O operation
Retrieve the return status of an asynchronous I/O operation and free any
associated system resources
Request cancellation of a pending asynchronous I/O operation
Initiate synchronization of the media image of a file to which asynchronous
operations have been addressed

The question here is:

iIs aio.h interface not sufficient in some way? If not, what facility is it
missing? If it is sufficient, then just depend on the available
implementation or re-implement the interface in the most convenient way.
