aio_error - get error status of asynchronous I/O operation

#include <aio.h>
int aio_error(const struct aiocb *aiocbp);

The aio_error() function returns the error status for the asynchronous I/O request with control block pointed to by aiocbp. (See aio(7) for a description of the aiocb structure.)

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.

> 0

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.

See aio(7).
