Memory Manager Routines

Manipulating Heap Zones

The Memory Manager provides several routines for initializing and resizing heap zones.

To obtain information about the current application partition, applications can call the GetApplLimit function and the TopMem function. If your application uses the stack extensively, you might want to ensure that the stack is set to at least some minimum size, at the expense of the heap. To do so, use the SetApplLimit procedure to change the application heap limit before you call the MaxApplZone procedure.

To initialize a new heap zone, use the InitZone procedure. The Operating System automatically initializes the application zone by calling the SetApplBase procedure, which subsequently calls the InitApplZone procedure.
