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 , const struct timespec * timeout );
DESCRIPTION
io_queue_wait () attempts to read an event from the completion queue for the aio_context specified by ctx .
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.
