Hi, all.

I'm not trying to use Temporary Memory.
I read the Inside Macintosh : Memory Chapter 2-10 but I could not understand
several description about it.

(1) If temporary-memory handles are not real, then you cannot use normal
Memory Manager routines such as HLock to manipulate them.

How can I lock it up or unlock it? I think I have to use 

MemoryHd& = FN tempNewHandle(size&,osErr)
call TempDisposeHandle(MemoryHd&,osErr)
call tempHLock(MemoryHd&,osErr)
call tempHunLock(memoryHd&,osErr)

(Those toolbox calls may not be supported in FB. Does anyone have
converted?)

How can I distinguish temporary handle from normal memory manger's handle?
Can I use get state or set state?

(2) The Gestalt function includes a selector to determine whether the
temporary-memory
routines are present in the operating environment and, if they are, whether
the temporary-memory handles are tracked and whether they are real. If
temporary-memory handles are not tracked, you must release temporary memory
before
your next call to GetNextEvent or WaitNextEvent.

What's GetNextEvent or WaitNextEvent? I guess this is same as HANDLEEVENTS.
This topic was explained in Tecnotes form apple, but I cannot understand
because it's very hard...

Therefore, I'm seeking sample code in FB. The best way to understand of this
topic is see the good code, I think. Is there anyone who had done this work?

I want to compress off-world to JPEG, and I have to allocate a handle to
temporary for compressor. Sometimes the off-world is very large and fail to
allocate a handle from application heap. In this case, I guess I have to use
temp memory, right?

TIA.
