NAME

aio_error - get error status of asynchronous I/O operation  

LIBRARY

Rea-time library (librt,~-lrt)  

SYNOPSIS

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

 

DESCRIPTION

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.)  

RETURN VALUE

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.

 

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.

ENOSYS

aio_error() is not implemented.
