|AIO_SUSPEND(2)||System Calls Manual||AIO_SUSPEND(2)|
LIBRARY¶Standard C Library (libc, -lc)
struct aiocb *const iocbs,
const struct timespec
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 iocbs argument is an array of niocb pointers to asynchronous I/O requests. Array members containing null pointers will be silently ignored.
If timeout is not a null pointer, it specifies a maximum interval to suspend. If timeout is a null pointer, the suspend blocks indefinitely. To effect a poll, the timeout should point to a zero-value timespec structure.
RETURN VALUES¶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.
aio_suspend() system call will fail if:
SEE ALSO¶aio_cancel(2), aio_error(2), aio_return(2), aio_waitcomplete(2), aio_write(2), aio(4)
aio_suspend() system call is expected to conform to the IEEE Std 1003.1 (“POSIX.1”) standard.
aio_suspend() system call first appeared in FreeBSD 3.0.
