49    DESCRIPTION
50    io_cancel attempts to cancel an asynchronous I/O operation  previously
51    submitted  with  the io_submit system call.  ctx_id is the AIO context
52    ID of the operation to be cancelled.  If the AIO context is found, the
53    event  will be cancelled and then copied into the memory pointed to by
54    result without being placed into the completion queue.
55 
56    RETURN VALUE
57    io_cancel returns 0 on success; otherwise, it returns one of  the  er-
58    rors listed in the "Errors" section.
59 
60    ERRORS
61    EINVAL The AIO context specified by ctx_id is invalid.
62 
63    EFAULT One of the data structures points to invalid data.
