[Scummvm-devel] Fwd: SCI mem functions

[Oystein Eftevaag]

It -can- be a matter of recovery as well, if you're using any caches and 
other memory that might not be used right now and will be reallocated at 
need. The memory functions would simply check the result from the OS 
malloc call, free up the caches if it fails, then try again.

I'm guessing we don't use a lot of caches, though :).

But yes, printing a simple assert message when you run out of memory 
would probably be a good idea (you could also print other details like 
attempted allocation size and total memory usage).

But IMO this should still be platform specific. And definately NOT use 
any wrapper functions that'll replace new/malloc/free/delete everywhere, 
but rather hook the functions directly like I explained earlier.
