According to Apple, the -drain method is a synonym for -release (or -dealloc since you don't retain autorelease pools).
So yes, if youi drain a pool the next time an object is autoreleased it goes into the parent pool of the one you drained.
Your code above should crash at the point where you call [innerPool release] since you are sending the -release message to a deallocated object.

Thank you! I guess I never read that part of the NSAutoreleasePool docs.

 

I think the -drain method name is unintuitive.  To me it sounds like it ought to do the same as the gnustep-specific -emptyPool method (a more efficient equivalent to draining/releasing the pool and immediately creating a new one).

That's what I assumed it was doing: releasing the members of the pool, while not releasing the pool itself.

Thank you!
