NAME
io_queue_wait - Wait for io requests to complete
SYNOPSIS
#include <errno.h>
#include <libaio.h>
int io_queue_wait(io_context_t ctx_id, const struct timespec *timeout);
DESCRIPTION
Attempts to read an event from the completion queue for the aio_context
specified by ctx_id.
RETURN VALUES
May return 0 if no events are available and the timeout specified by
when has elapsed, where when == NULL specifies an infinite timeout.
Note that the timeout pointed to by when is relative and will be
updated if not NULL and the operation blocks. Will fail with -ENOSYS
if not implemented.
RETURN VALUES
On success, io_queue_wait returns 0. Otherwise, -error is return, where
error is one of the Exxx values defined in the Errors section.
ERRORS
EFAULT iocbs referenced data outside of the program’s accessible
address space.
EINVAL ctx_id refers to an unitialized aio context, the iocb pointed to
by iocbs contains an improperly initialized iocb.
ENOSYS Not implemented.
