AIO_SUSPEND(3P)		   POSIX Programmer's Manual	       AIO_SUSPEND(3P)

       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the	 corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.

       aio_suspend — wait for an asynchronous I/O request

       #include <aio.h>

       int aio_suspend(const struct aiocb *const list[], int nent,
	   const struct timespec *timeout);

       The aio_suspend() function shall suspend the calling  thread  until  at
       least  one  of  the  asynchronous I/O operations referenced by the list
       argument has completed, until a signal interrupts the function, or,  if
       timeout	is  not NULL, until the time interval specified by timeout has
       passed. If any of the aiocb structures in the list correspond  to  com‐
       pleted  asynchronous  I/O operations (that is, the error status for the
       operation is not equal to [EINPROGRESS]) at the time of the  call,  the
       function	 shall	return without suspending the calling thread. The list
       argument is an array of pointers to asynchronous	 I/O  control  blocks.
       The  nent  argument indicates the number of elements in the array. Each
       aiocb structure pointed to has been used in initiating an  asynchronous
       I/O  request  via aio_read(), aio_write(), or lio_listio().  This array
       may contain null pointers, which are ignored. If	 this  array  contains
       pointers that refer to aiocb structures that have not been used in sub‐
       mitting asynchronous I/O, the effect is undefined.

       If the time interval indicated in the timespec structure pointed to  by
       timeout	passes before any of the I/O operations referenced by list are
       completed, then aio_suspend() shall return with an error.  If the Mono‐
       tonic  Clock  option is supported, the clock that shall be used to mea‐
       sure this time interval shall be the CLOCK_MONOTONIC clock.

       If the aio_suspend() function returns after one	or  more  asynchronous
       I/O  operations	have completed, the function shall return zero. Other‐
       wise, the function shall return a value of −1 and set errno to indicate
       the error.

       The application may determine which asynchronous I/O completed by scan‐
       ning the associated error  and  return  status  using  aio_error()  and
       aio_return(), respectively.

       The aio_suspend() function shall fail if:

       EAGAIN No  asynchronous	I/O  indicated	in the list referenced by list
	      completed in the time interval indicated by timeout.

       EINTR  A signal interrupted  the	 aio_suspend()	function.  Note	 that,
	      since  each  asynchronous	 I/O  operation may possibly provoke a
	      signal when it completes, this error return may be caused by the
	      completion  of  one  (or	more) of the very I/O operations being
