Hi,
I did call sem_init:
sem_init(&lampion,NULL,0);


Casting the pointer is ugly. Better to use a real 'void *' and pass its
address to pthread_join, you can then cast the 'void *'. The problem is
that
a 'void *' might not be the same size or same format as an 'int'.
Casting
the address doesn't give the compiler the ability to fix that.
-> Yes, but I used this in other multithreaded programs, and never gave
any problem. I found it in pthread-primers (a book).
Do you allso happen to know what might be wrong with my semaphore? Or,
how I should do what I described, without a semaphore (although I
prefer to use a semaphore, since it's made for such a kind of
things...)?

Thanks.
