16
17 int aio_error(const struct aiocb *aiocbp);
18
20 The aio_error() function shall return the error status associated with
21 the aiocb structure referenced by the aiocbp argument. The error status
22 for an asynchronous I/O operation is the errno value that would be set
23 by the corresponding read(), write(), fdatasync(), or fsync() opera‐
24 tion. If the operation has not yet completed, then the error status
25 shall be equal to [EINPROGRESS].
26
27 If the aiocb structure pointed to by aiocbp is not associated with an
28 operation that has been scheduled, the results are undefined.
29
31 If the asynchronous I/O operation has completed successfully, then 0
32 shall be returned. If the asynchronous operation has completed unsuc‐
33 cessfully, then the error status, as described for read(), write(),
34 fdatasync(), and fsync(), shall be returned. If the asynchronous I/O
35 operation has not yet completed, then [EINPROGRESS] shall be returned.
36
37 If the aio_error() function fails, it shall return -1 and set errno to
38 indicate the error.
39
41 The aio_error() function may fail if:
42
43 EINVAL The aiocbp argument does not refer to an asynchronous operation
44 whose return status has not yet been retrieved.
