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);


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(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.

CONFORMING TO
       POSIX 1003.1-2003
