aio_suspend — wait for asynchronous I/O operation or timeout
#include <aio.h>
int
aio_suspend( |
const struct aiocb * const | cblist[], |
int | n, | |
const struct timespec * | timeout) ; |
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.
If this function returns after completion of one of the
indicated requests, it returns 0. Otherwise it returns
−1 and sets errno
appropriately.
The call was ended by timeout, before any of the indicated operations had completed.
The call was ended by signal. (Possibly the completion signal of one of the operations we were waiting for.)
