aio_suspend
—
suspend until asynchronous I/O operations or timeout
complete (REALTIME)
Standard C Library (libc, -lc)
#include
<aio.h>
int
aio_suspend
(const struct aiocb *const
list[], int nent, const struct
timespec *timeout);
The
aio_suspend
()
system call suspends the calling process until at least one of the specified
asynchronous I/O requests have completed, a signal is delivered, or the
timeout has passed.
The list argument is an array of nent pointers to asynchronous I/O requests. Array members containing NULL will be silently ignored.
If timeout is a non-nil pointer, it specifies a maximum interval to suspend. If timeout is a nil pointer, the suspend blocks indefinitely. To effect a poll, the timeout should point to a zero-value timespec structure.
If one or more of the specified asynchronous I/O requests have
completed, aio_suspend
() returns 0. Otherwise, it
returns -1 and sets errno to indicate the error, as
enumerated below.
The aio_suspend
() system call will fail
if:
aio_cancel(2), aio_error(2), aio_return(2), aio_write(2), aio(4)
The aio_suspend
() system call is expected
to conform to the IEEE Std 1003.1
(“POSIX.1”) standard.
The aio_suspend
() system call first
appeared in FreeBSD 3.0.
