AIO_ERROR(3P) POSIX Programmer's Manual AIO_ERROR(3P)
This manual page is part of the POSIX Programmer's Manual. The
Linux implementation of this interface may differ (consult the
corresponding Linux manual page for details of Linux behavior), or
the interface may not be implemented on Linux.
aio_error — retrieve errors status for an asynchronous I/O
operation
#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 aiocb structure pointed to by aiocbp is not associated with
an operation that has been scheduled, the results are undefined.
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.
If the aio_error() function fails, it shall return -1 and set
errno to indicate the error.
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.
