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

NAME         top

       aio_return - get return status of asynchronous I/O operation

SYNOPSIS         top

       #include <aio.h>

       ssize_t aio_return(struct aiocb *aiocbp);

       Link with -lrt.

DESCRIPTION         top

       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 EINPROGRESS.

RETURN VALUE         top

       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         top

       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         top

       POSIX.1-2001.
