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



 

NAME


       aio_return - get return status of asynchronous I/O operation

 

SYNOPSIS


       #include 

       ssize_t aio_return(struct aiocb *aiocbp);

       Link with -lrt.

 

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(3) 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.1-2001.
