While Carbon supports most of the Memory Management Utilities, there are changes to functions that assume a 68K runtime environment.
Functions that flush caches on 68K processors (such as FlushInstructionCache, FlushDataCache, and FlushCodeCacheRange) are no longer supported.
Functions such as SetA5 or SetCurrentA5 do nothing when running in Mac OS X. However, these functions should work normally when running in Mac OS 8.
The functions GetMMUMode and SwapMMUMode are not supported because all PowerPC applications use 32-bit addressing, even if they are not Carboncompliant.
The SysEnvirons function is no longer supported since the Gestalt Manager can provide the same information. You should call the functions FindFolder and Gestalt instead.
