|AIO_WAITCOMPLETE(2)||System Calls Manual||AIO_WAITCOMPLETE(2)|
wait for the next completion of an aio request
Standard C Library (libc, -lc)
aiocb **iocbp, struct
system call waits for completion of an asynchronous I/O request. Upon
aio_waitcomplete() returns the result of
the function and sets iocbp to point to the structure
associated with the original request. If an asynchronous I/O request is
aio_waitcomplete() is called, it
returns immediately with the completed request.
If timeout is a
non-NULL pointer, it specifies a maximum interval to wait for a asynchronous
I/O request to complete. If timeout is a NULL pointer,
waits indefinitely. To effect a poll, the timeout
argument should be non-NULL, pointing to a zero-valued timeval
If an asynchronous I/O request has completed,
iocbp is set to point to the control block passed with
the original request, and the status is returned as described in
read(2), write(2), or
fsync(2). On failure,
-1, sets iocbp to
sets errno to indicate the error condition.
aio_waitcomplete() system call fails
- The specified time limit is invalid.
- The process has not yet called
- A signal was delivered before the timeout expired and before any asynchronous I/O requests completed.
- The specified time limit expired before any asynchronous I/O requests completed.
aio_waitcomplete() system call is a

appeared in FreeBSD 4.0.
