NAME

6       aio_suspend - wait for asynchronous I/O operation or timeout
7

SYNOPSIS

9       #include <aio.h>
10
11       int aio_suspend(const struct aiocb * const cblist[],
12                       int n, const struct timespec *timeout);

DESCRIPTION

16       The  aio_suspend() function suspends the calling process until at least
17       one of the asynchronous I/O requests in the list  cblist  of  length  n
18       have  completed,  a signal is delivered, or timeout is not NULL and the
19       time interval it indicates has passed.
20
21       Each item in the list must either be NULL (and then is ignored),  or  a
22       pointer   to   a  control  block  on  which  I/O  was  initiated  using
23       aio_read(3), aio_write(3), or lio_listio(3).
24
25       If CLOCK_MONOTONIC is supported, this clock  is  used  to  measure  the
26       timeout interval.
27

RETURN VALUE

29       If  this  function  returns  after  completion  of one of the indicated
30       requests, it returns 0. Otherwise it returns -1 and sets  errno  appro‐
31       priately.
32

ERRORS

34       EAGAIN The call was ended by timeout, before any of the indicated oper‐
35              ations had completed.
36
37       EINTR  The call was ended by signal.  (Possibly the  completion  signal
38              of one of the operations we were waiting for.)
39

NOTE

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