Function drmgr_register_restore_state_ex_event_ex 

pub unsafe extern "C" fn drmgr_register_restore_state_ex_event_ex(
    func: Option<unsafe extern "C" fn(drcontext: *mut c_void, restore_memory: bool_, info: *mut dr_restore_state_info_t) -> bool_>,
    priority: *mut drmgr_priority_t,
) -> bool_

Registers a callback function for the restore state extended event, which behaves just like DR’s restore state event dr_register_restore_state_ex_event(), except that it is ordered according to \p priority among both extended and regular callbacks. A default priority of 0 is used for events registered via drmgr_register_restore_state_event() or drmgr_register_restore_state_ex_event(). Just like for DR, the first callback to return false will short-circuit event delivery to later callbacks. \return whether successful.
