Yes,
enEventClasses is an enum so I am just casting it to an UInt32,
as per the Xcode Reference:
struct EventTypeSpec {
UInt32 eventClass;
UInt32 eventKind;
};
typedef struct EventTypeSpec EventTypeSpec;
Heres one strange thing though - actually I found out yesterday that by
forgetting to include Byref , for the version of the project that WORKS, the
structure holding the array of eventtypespecs isnt actually being filled. If
I actually fill the structure I get a crash. A mystery - passing a non zero
eventcount along with an empty event struct works fine in the Carbon
version.
