hgello,
? How many allocations of about 64K can one do?
in the storage heap? as many as will fit.
? What if I need to load an entire record, is it possible to load all that data, about 64K into a dynamically allocated buffer If I were to say parse XML, would it make sense to load as much as I can into memory and operate on that for speed or should I iterate the data directly w/in the storage heap?
speed? reading storage and dynamic heap is the same speed they are on the same RAM chip. writing to storage in supported methods is slow, but MemSemaphore* functions are supported in all m68k devices.
