22 The aio_error() function shall return the error status associated with
23 the aiocb structure referenced by the aiocbp argument. The error status
24 for an asynchronous I/O operation is the errno value that would be set
25 by the corresponding read(), write(), fdatasync(), or fsync() opera‐
26 tion. If the operation has not yet completed, then the error status
27 shall be equal to [EINPROGRESS].
28
30 If the asynchronous I/O operation has completed successfully, then 0
31 shall be returned. If the asynchronous operation has completed unsuc‐
32 cessfully, then the error status, as described for read(), write(),
33 fdatasync(), and fsync(), shall be returned. If the asynchronous I/O
34 operation has not yet completed, then [EINPROGRESS] shall be returned.
35
37 The aio_error() function may fail if:
38
39 EINVAL The aiocbp argument does not refer to an asynchronous operation
40 whose return status has not yet been retrieved.

49 The aio_error() function is part of the Asynchronous Input and Output
50 option and need not be available on all implementations.
