NAME

aio_return - retrieve return status of asynchronous I/O operation (REALTIME)

LIBRARY


.Lb libc

SYNOPSIS


.In aio.h ssize_t 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 asynchronous I/O request.

STANDARDS

The aio_return system call is expected to conform to the -p1003.1 standard.

HISTORY

The aio_return system call first appeared in
.Fx 3.0 .
