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.

ERRORS

       EFAULT iocbs referenced data outside of the program's accessible address space.

       EINVAL ctx refers to an uninitialized aio context, the iocb pointed to by  iocbs  contains
              an improperly initialized iocb.

       ENOSYS Not implemented.
