aio_suspend(2)

The  system  call suspends the calling process until at least one
of the specified asynchronous I/O requests have completed, a sig‐
nal is delivered, or the has passed.  The argument is an array of
pointers to asynchronous I/O requests.  Array members  containing
null  pointers  will  be  silently  ignored.   If  is  not a null
pointer, it specifies a maximum interval to  suspend.   If  is  a
null pointer, the suspend blocks indefinitely.  To effect a poll,
the  should  point to a zero-value timespec structure.  If one or
more of the specified asynchronous I/O requests  have  completed,
returns  0.  Otherwise it returns -1 and sets to indicate the er‐
ror, as enumerated below.  The system call will fail if: the  ex‐
pired  before  any I/O requests completed.  The argument contains
more asynchronous I/O requests than the variable, or at least one
of the requests is not valid.  the suspend was interrupted  by  a
signal.   The system call is expected to conform to the standard.
