Linux 2.6 - man page for aio_error (linux section 3)

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.  (See aio(7) for a description  of  the  aiocb  struc-
       ture.)

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.

       *  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.

VERSIONS
       The aio_error() function is available since glibc 2.1.

ATTRIBUTES

       The aio_error() function is thread-safe.

CONFORMING TO
