Manager: Memory Management Utilities

While Carbon will support 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) will no longer be supported.

* Functions such as SetA5 or SetCurrentA5 will 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 will not be supported because all PowerPC applications use 32-bit addressing, even if they are not Carbon–compliant.

* The SysEnvirons function will no longer be supported since the Gestalt Manager can provide the same information. You should call the functions FindFolder and Gestalt instead.

 FlushCodeCache

68K-specific.

68K-specific.

 FlushInstructionCache

68K-specific. Use MakeDataExecutable on PowerPC machines.

68K-specific. Does nothing in PowerPC native code.

 SetCurrentA5

68K-specific. Does nothing in PowerPC native code.

 SwapDataCache

 SwapInstructionCache

 SwapMMUMode

Not necessary on PowerPC, since all native PowerPC applications use 32-bit addressing.
