AIO_SUSPEND(3)		   Linux Programmers Manual	       AIO_SUSPEND(3)



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

SYNOPSIS
       #include 

       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	appro
       priately.

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

       EINTR  The call was ended by signal; see signal(7).  (Possibly the com
	      pletion 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.
