Technical Q&A ME03
Determining the State of the Modern Memory Manager

Q: How do I determine if I am running with the Modern Memory Manager?

A: You can tell the state of MMM based on the heapType member in your current Zone. The following function shows how this is done: 

#include <Memory.h>
/*
** HaveNewMemoryManager returns true if the new
** Memory Manager is present
*/

Boolean HaveNewMemoryManager ( void ) {
    THz appZone;

    appZone = GetZone ();
    return ((appZone->heapType & kNewStyleHeap) != 0);
}
