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