NAME

aio_suspend — suspend until asynchronous I/O operations or timeout complete (REALTIME)

LIBRARY

Standard C Library (libc, -lc)

SYNOPSIS

#include <aio.h> int aio_suspend(const struct aiocb *const iocbs[], int niocb, const struct timespec *timeout);

DESCRIPTION

The aio_suspend() system call suspends the calling process until at least one of the speci‐ fied 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 mem‐ bers 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.

ERRORS

The aio_suspend() system call will fail if: [EAGAIN] the timeout expired before any I/O requests completed. [EINVAL] The iocbs argument contains more than AIO_LISTIO_MAX asynchronous I/O requests, or at least one of the requests is not valid. [EINTR] the suspend was interrupted by a signal.

STANDARDS

The aio_suspend() system call is expected to conform to the IEEE Std 1003.1 (“POSIX.1”) standard.

HISTORY

The aio_suspend() system call first appeared in FreeBSD 3.0.
