DESCRIPTION
Theaio_error()
system call returns the error status of the asynchronous I/O request
associated with the structure pointed to by iocb.
RETURN VALUES
If the asynchronous I/O request has completed successfully,
aio_error() returns 0. If the request has not yet
completed, EINPROGRESS is returned. If the request
has completed unsuccessfully the error status is returned as described in
read(2),
write(2), or
fsync(2). On failure, aio_error() returns
-1 and sets errno to
indicate the error condition.
ERRORS
The aio_error() system call will fail
if:
- [
EINVAL] - The iocb argument does not reference an outstanding asynchronous I/O request.
