AIO_RETURN(3)                                       Linux Programmer's Manual                                      AIO_RETURN(3)



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

SYNOPSIS
       #include <aio.h>

       ssize_t aio_return(struct aiocb *aiocbp);

       Link with -lrt.

DESCRIPTION
       The  aio_return() function returns the final return status for the asynchronous I/O request with control block pointed to
       by aiocbp.

       This function should be called only once for any given request, after aio_error(3)  returns  something  other  than  EIN-
       PROGRESS.

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.

CONFORMING TO
       POSIX.1-2001.
