Why can't you ask all your questions at once?

The answer to your last one is in the manpage. size_t, as
name suggests, is used for sizes of various memory regions,
in bytes. Here, we're dealing with something else, not bytes.

And probably the next question will be of the sort why the argument
is named 'event' and not 'Event' or 'EventPtr', and why there's no
space after the star character... Oh well.
