Thank you. I think this will now do.

This seems to be a recurrent behaviour in the BSDs: the functions return 
the actual number of items/bytes stored, instead of the full length that 
would be expected. I found the same problem recently on 
getsockname()/getpeername(), even though the BSDi man page was very 
specific about the behaviour.

I fail to see how it would be useful to return the actual number stored...
