15 The aio_return() function returns the final return status for the asyn‐
16 chronous I/O request with control block pointed to by aiocbp.
17
18 This function should be called only once for any given request, after
19 aio_error(3) returns something other than EINPROGRESS.
20
22 If the asynchronous I/O operation has completed, this function returns
23 the value that would have been returned in case of a synchronous read,
24 write, or fsync request. Otherwise the return value is undefined. On
25 error, the error value is returned.
26
28 EINVAL aiocbp does not point at a control block for an asynchronous I/O
29 request of which the return status has not been retrieved yet.
