Re: does NSLog take ownership of the NSString it is given?

[Dan Hitt]

To follow up on my own post here:

Richard: thanks again for your kind help, which i really appreciate.

I was terribly remiss in not looking at NSString.h before posting.

The comments in that file naturally back you up: if i want to RELEASE
the string myself, i can just use one of the -init... methods (such as
-initWithFormat:)

I'm still unclear about when temporary strings get free'd (other
than when the pool they come from gets free'd), and i'd appreciate
any pointers from anybody on just what the connection is between
the autorelease pool one creates in main() and its eventual usage
(and how it gets passed around), but for now i can just use alloc/init...
code.

Thanks again to everybody who has helped me, and everybody who is
putting together this gnustep creation.
