aio_error - retrieve errors status for an asynchronous I/O operation (
REALTIME)
Návod, kniha: POSIX Programmer's Manual
#include <aio.h>
int aio_error(const struct aiocb *
aiocbp);
The
aio_error() function shall return the error status associated with
the
aiocb structure referenced by the
aiocbp argument. The error
status for an asynchronous I/O operation is the
errno value that would
be set by the corresponding
read(),
write(),
fdatasync(),
or
fsync() operation. If the operation has not yet completed, then the
error status shall be equal to [EINPROGRESS].
If the asynchronous I/O operation has completed successfully, then 0 shall be
returned. If the asynchronous operation has completed unsuccessfully, then the
error status, as described for
read(),
write(),
fdatasync(), and
fsync(), shall be returned. If the asynchronous
I/O operation has not yet completed, then [EINPROGRESS] shall be returned.
The
aio_error() function may fail if:
- EINVAL
- The aiocbp argument does not refer to an
asynchronous operation whose return status has not yet been retrieved.
The following sections are informative.

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