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 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.

       *  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.
