AIO_SUSPEND(3) Linux Programmer's Manual AIO_SUSPEND(3)NAMEaio_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);
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. (Possibly the completion signal
of one of the operations we were waiting for.)
NOTE
One can achieve polling by using a non-NULL timeout that specifies a
zero time interval.
