NAME
       aio_return - get return status of asynchronous I/O operation

SYNOPSIS
       #include <aio.h>

       ssize_t aio_return(struct aiocb *aiocbp);


DESCRIPTION
       The  aio_return function returns the final return status for the asyn-
       chronous I/O request with control block pointed to by aiocbp.

       This function should be called only once for any given request,	after
       aio_error(2) returns something other than EINPROGRESS.

RETURN VALUE
       If the asynchronous I/O operation has completed, this function returns
       the value that would have been returned in case of a synchronous read,
       write, or fsync request.	 Otherwise the return value is undefined.  On
       error, the error value is returned.

ERRORS
       EINVAL aiocbp does not point at a control block	for  an	 asynchronous
	      I/O  request  of which the return status has not been retrieved
	      yet.
