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



NAME
       aio_error - get error(8,n) status of asynchronous I/O operation

SYNOPSIS
       #include <aio.h>

       int aio_error(const struct aiocb *aiocbp);


DESCRIPTION
       The  aio_error  function  returns the error(8,n) status for the asynchronous
       I/O request with control block pointed to by aiocbp.

RETURN VALUE
       This function returns EINPROGRESS if(3,n) the request has not been completed
       yet.  It  returns ECANCELED if(3,n) the request was cancelled.  It returns 0
       if(3,n) the request completed successfully.  Otherwise  an  error(8,n)  value  is
       returned, the same value that would have been stored in(1,8) the errno vari-
       able in(1,8) case of a synchronous read(2,n,1 builtins), write(1,2), fsync, or fdatasync request.
       On error(8,n), the error(8,n) 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 1003.1-2003
