struct kevent {
uintptr_t ident; /* identifier for this event */
short filter; /* filter for event */
u_short flags; /* action flags for kqueue */
u_int fflags; /* filter flag value */

union {
u32 _data_padding[2];
intptr_t data; /* filter data value */
};

union {
u32 _udata_padding[2];
void *udata; /* opaque user data identifier */
};
};

I'm not missing anything obvious here, I hope.
