AIO_RETURN(2)		    BSD System Calls Manual		 AIO_RETURN(2)

NAME
     aio_return — retrieve return status of asynchronous I/O operation (REAL‐
     TIME)

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <aio.h>

     int
     aio_return(struct aiocb *iocb);

DESCRIPTION
     The aio_return() system call returns the final status of the asynchronous
     I/O request associated with the structure pointed to by iocb.

     The aio_return() system call should only be called once, to obtain the
     final status of an asynchronous I/O operation once it has completed
     (aio_error(2) returns something other than EINPROGRESS).

RETURN VALUES
     If the asynchronous I/O request has completed, the status is returned as
     described in read(2), write(2), or fsync(2).  Otherwise, aio_return()
     returns -1 and sets errno to indicate the error condition.

ERRORS
     The aio_return() system call will fail if:

     [EINVAL]		The iocb argument does not reference a completed asyn‐
			chronous I/O request.

SEE ALSO
     aio_cancel(2), aio_error(2), aio_suspend(2), aio_waitcomplete(2),
     aio_write(2), fsync(2), read(2), write(2), aio(4)

STANDARDS
     The aio_return() system call is expected to conform to the IEEE Std
     1003.1 (“POSIX.1”) standard.

HISTORY
     The aio_return() system call first appeared in FreeBSD 3.0.
