aio_error - get error status of asynchronous I/O operation
int aio_error(const struct aiocb *aiocbp);
Link with -lrt.
The aio_error() function returns the error status for the asynchronous
I/O request with control block pointed to by aiocbp.
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 vari
able in case of a synchronous read, write, fsync, or fdatasync request.
On error, the error value is returned.
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.
