aio_error - get error status of asynchronous I/O operation
int aio_error(const struct aiocb *
This function returns one of the following:
EINPROGRESS, if the request has not been completed yet.
ECANCELED, if the request was canceled.
0, if the request completed successfully.
A positive error number, if the asynchronous I/O operation failed. This is the same value that would have been stored in the
errno variable in the case of a synchronous read(2), write(2), fsync(2), or fdatasync(2) call.
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.
aio_error() is not implemented.
For an explanation of the terms used in this section, see attributes(7).
