|
|
896 | aio_ioctl $fh, $request, $buf, $callback->($status) |
|
|
897 | These work just like the "fcntl" and "ioctl" built-in functions, |
|
|
898 | except they execute asynchronously and pass the return value to the |
|
|
899 | callback. |
|
|
900 | |
|
|
901 | Both calls can be used for a lot of things, some of which make more |
|
|
902 | sense to run asynchronously in their own thread, while some others |
|
|
903 | make less sense. For example, calls that block waiting for external |
|
|
904 | events, such as locking, will also lock down an I/O thread while it |
|
|
905 | is waiting, which can deadlock the whole I/O system. At the same |
|
|
906 | time, there might be no alternative to using a thread to wait. |
|
|
907 | |
|
|
908 | So in general, you should only use these calls for things that do |
|
|
909 | (filesystem) I/O, not for things that wait for other events |
|
|
910 | (network, other processes), although if you are careful and know |
|
|
911 | what you are doing, you still can. |
