SYNOPSIS


.In aio.h int aio_suspend "const struct aiocb * const iocbs[]" "int niocb" "const struct timespec * timeout"

DESCRIPTION

The aio_suspend system call suspends the calling process until at least one of the specified asynchronous I/O requests have completed, a signal is delivered, or the timeout has passed.

The iocbs argument is an array of niocb pointers to asynchronous I/O requests. Array members containing null pointers will be silently ignored.

If timeout is not a null pointer, it specifies a maximum interval to suspend. If timeout is a null pointer, the suspend blocks indefinitely. To effect a poll, the timeout should point to a zero-value timespec structure.

RETURN VALUES

If one or more of the specified asynchronous I/O requests have completed, aio_suspend returns 0. Otherwise it returns -1 and sets errno to indicate the error, as enumerated below.

ERRORS

The aio_suspend system call will fail if:
[EAGAIN]
the timeout expired before any I/O requests completed.
[EINVAL]
The iocbs argument contains more than AIO_LISTIO_MAX asynchronous I/O requests, or at least one of the requests is not valid.
[EINTR]
the suspend was interrupted by a signal.
