DESCRIPTION
     The aio_error() system call returns the error status of the asynchronous
     I/O request associated with the structure pointed to by iocb.

     returns 0.	 If the	request	has not	yet completed, EINPROGRESS is
     returned.	If the request has completed unsuccessfully the	error status
     is	returned as described in read(2), write(2), or fsync(2)	is returned.
     On	failure, aio_error() returns -1	and sets errno to indicate the error
     condition.

     The aio_error() system call will fail if:

     [EINVAL]		The iocb argument does not reference an	outstanding
			asynchronous I/O request.
