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.
