AIO_ERROR(3)                                        Linux Programmer's Manual                                       AIO_ERROR(3)



NAME
       aio_error - get error status of asynchronous I/O operation

SYNOPSIS
       #include <aio.h>

       int aio_error(const struct aiocb *aiocbp);

       Link with -lrt.

DESCRIPTION
       The  aio_error()  function  returns  the  error  status for the asynchronous I/O request with control block pointed to by
       aiocbp.

RETURN VALUE
       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 variable in case of a synchronous read,  write,  fsync,  or  fdatasync  request.   On
       error, the error value is returned.

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.

CONFORMING TO
       POSIX.1-2001.
