aio_return2freebsd

Usage

Library

Standard C Library (libc, -lc)

Overview

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.
