#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.

This function returns EINPROGRESS if the request has not been completed yet. It returns ECANCELED if the request was cancelled. 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.

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.
