  DESCRIPTION
       io_destroy  removes  the asynchronous I/O context from the list of I/O
       contexts and then destroys it.  io_destroy can also  cancel  any  out-
       standing asynchronous I/O actions on ctx and block on completion.

 RETURN VALUE
       io_destroy returns 0 on success.

 ERRORS
       EINVAL The AIO context specified by ctx is invalid.
