The
aio_error()
function returns the error status for the asynchronous I/O request
with control block pointed to by
aiocbp.
RETURN VALUE
This function returns
EINPROGRESS
if the request has not been
completed yet.
It returns
ECANCELED
if the request was canceled.
It returns 0 if the request completed successfully.
Otherwise an error value is returned, the same value that would have
been stored in the
errno
variable in case of a synchronous
read,
write,
fsync,
or
fdatasync
request.
On error, the error value is returned.
ERRORS
EINVAL
aiocbp
does not point at a control block for an asynchronous I/O request
of which the return status (see
aio_return(3))
has not been retrieved yet.
