AIO_RETURN(3P)		   POSIX Programmer's Manual		AIO_RETURN(3P)

       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the	 corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.

       aio_return — retrieve return status of an asynchronous I/O operation

       #include <aio.h>

       ssize_t aio_return(struct aiocb *aiocbp);

       The aio_return() function shall return  the  return  status  associated
       with  the aiocb structure referenced by the aiocbp argument. The return
       status for an asynchronous I/O operation is the	value  that  would  be
       returned	 by  the  corresponding	 read(),  write(), or fsync() function
       call. If the error status for the operation is equal to	[EINPROGRESS],
       then the return status for the operation is undefined. The aio_return()
       function may be called exactly once to retrieve the return status of  a
       given  asynchronous  operation; thereafter, if the same aiocb structure
       is used in a call to aio_return()  or  aio_error(),  an	error  may  be
       returned.  When	the  aiocb  structure referred to by aiocbp is used to
       submit another asynchronous operation, then aio_return()	 may  be  suc‐
       cessfully used to retrieve the return status of that operation.

       If  the	asynchronous I/O operation has completed, then the return sta‐
       tus, as described for read(), write(), and fsync(), shall be  returned.
       If the asynchronous I/O operation has not yet completed, the results of
       aio_return() are undefined.

       If the aio_return() function fails, it shall return −1 and set errno to
       indicate the error.

       The aio_return() function may fail if:

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