Hi,

It is not possible that all information is filled in with each event.
For example, there is no "mode" for ON_CLOSE events. This value only
makes sense for ON_OPEN events.

Since there is no guarenteed way to represent an unset value, each value
has a separate set_xxx boolean. If the boolean is set to false, then
Dazuko was not able to determine a value for that item.

For example, if uid == 0 and set_uid != 0, then you know that the event
was triggered by a root process. But if uid == 0 and set_uid == 0, then
this means that Dazuko was unable to determine which user triggered the
event.

In summary, the field XXX only has meaning if set_XXX is nonzero.
