42 function suspends the calling process until at least one of the
43 specified asynchronous I/O requests have completed, a signal is
51 pointers to asynchronous I/O requests.
52 Array members containing NULL will be silently ignored.
56 is a non-nil pointer, it specifies a maximum interval to suspend.
59 is a nil pointer, the suspend blocks indefinitely.
62 should point to a zero-value timespec structure.
64 If one or more of the specified asynchronous I/O requests have

70 to indicate the error, as enumerated below.
74 function will fail if:
79 expired before any I/O requests completed.
