NAME
       aio_suspend - wait for asynchronous I/O operation or timeout

SYNOPSIS
       #include <aio.h>

       int aio_suspend(const struct aiocb * const cblist[],
		       int n, const struct timespec *timeout);

       Link with -lrt.

DESCRIPTION
       The  aio_suspend() function suspends the calling process until at least one of the asynchronous I/O requests in the list cblist of length n
       have completed, a signal is delivered, or timeout is not NULL and the time interval it indicates has passed.

       Each item in the list must either be NULL (and then is ignored), or a pointer  to  a  control  block  on  which	I/O  was  initiated  using
       aio_read(3), aio_write(3), or lio_listio(3).

       If CLOCK_MONOTONIC is supported, this clock is used to measure the timeout interval.

RETURN VALUE
       If this function returns after completion of one of the indicated requests, it returns 0.  Otherwise it returns -1 and sets errno appropri-
       ately.

ERRORS
       EAGAIN The call was ended by timeout, before any of the indicated operations had completed.

       EINTR  The call was ended by signal; see signal(7).  (Possibly the completion signal of one of the operations we were waiting for.)

CONFORMING TO
       POSIX.1-2001.

NOTES
       One can achieve polling by using a non-NULL timeout that specifies a zero time interval.
