I have this case:
extern int epoll_wait (int __epfd, struct epoll_event *__events,
                       int __maxevents, int __timeout);
And I would like to do it like:
<*EXTERNAL*> 
PROCEDURE epoll_wait (epfd: int; VAR events: ARRAY OF epoll_event; timeout: int := -1): int;
…
VAR
  events: ARRAY [0..MaxEvents-1] OF epoll_event;
…
WITH res = epoll_wait(epfd, events, 2) DO
  …
END;
Can I expect cm3 to do "right thing". Or I have to place parameters "by hand" using ADR and SIZE?
TIA,
dd
