34 .Nd retrieve return status of asynchronous I/O operation (REALTIME)
40 .Fn aio_return "struct aiocb *aiocbp"
44 system call returns the final status of the asynchronous I/O request
45 associated with the structure pointed to by
51 should only be called once, to obtain the final status of an asynchronous
52 I/O operation once it has completed
54 returns something other than
57 If the asynchronous I/O request has completed, the status is returned
67 to indicate the error condition.
71 system call will fail if:
77 does not reference a completed asynchronous I/O request.
91 is expected to conform to the
