AIO_ERROR(3)							  AIO_ERROR(3)

NAME    [Toc]    [Back]

     aio_error,	aio_error64 - return error status of an	asynchronous I/O
     operation

C SYNOPSIS    [Toc]    [Back]

     #include <aio.h>

     int aio_error(const aiocb_t *aiocbp);

     int aio_error64(const aiocb64_t *aiocbp);

DESCRIPTION    [Toc]    [Back]

     The aio_error() function returns the error	status associated with the
     aiocbp passed in. The error status	for an asynchronous I/O	operation is
     the errno value that would	be set by the corresponding read(2) or
     write(2) or fsync(2) operation.  If the operation has not yet completed,
     then the error status shall be equal to EINPROGRESS.

     The aio_error64() function	is identical to	aio_error() except that	it
     takes an aiocb64_t	* (see <aio.h>).  This structure allows	for the
     specification of a	file offset greater than 2 Gigabytes.  The user	must
     define _ABI_SOURCE	and include -labi to access the	aio64 routines.

     exec(2), fork(2).

DIAGNOSTICS    [Toc]    [Back]

     If	the asynchronous I/O operation has completed successfully, then	0
     shall be returned.	If the asynchronous operation has completed
     unsuccessfully, then the error status, as described for read(2),
     write(2), and fsync(2) shall be returned. If the asynchronous I/O has not
     yet completed, then EINPROGRESS shall be returned.

     If	any of the conditions below occur, the aio_error() function shall
     return -1 and set errno to	the corresponding value.

     [EINVAL]	    The	aiocbp argument	does not yet refer to an asynchronous
		    operation whose return status has not yet been retrieved.
