semget(2) - value of newly created semaphores?

[Johannes Sjogren]

I have a question about the behaviour of the semget(2) system call.

If I do

	semid = semget(SEMKEY, 1, 0777|IPC_CREAT);

and a new semaphore is created, is the value  of a newly created
semaphore guaranteed to be initialized to 0?

On DG/UX 4.30 the manual page for semget says this is the case.
On most other systems however the manual page says the value is undefined.
Is there any reason why the semaphore value shouldn't be reset to 0 
on creation? 
Maybe the (I suppose) system V derived "normal" manual pages are wrong?
