NSStream has the method

You throw in a NSInputStream** for an inputStream argument and
similar for the outputstream. Now my question is: What the heck is
the status for these streams? Did they got assigned autoreleased
streams or did I get something that is retained? I.e. should I do a
[inputStream retain] after this method or not??
Hrm. There really should at least be a comment in the documentation on
the web about that, but the standard Cocoa retain/release rules apply:
if you didn't create it via alloc/init, you should be doing your own
retain/releases on it.
In this case, the streams you get back from this call have already had
the autorelease message sent to them.
Thanks. I suspected this was the case, but then I saw code someone else
had written which seemingly omitted the retain, which made me a little
confused. Since this was the first time I actually called on a obj-c
message which used callbacks, I was not sure if the rules applied.
