Memory Management Routines

Grow-Zone Operations

You can implement a grow-zone function that the Memory Manager calls when it cannot fulfill a memory request. You should use the grow-zone function only as a last resort to free memory when all else fails.

The SetGrowZone procedure specifies which function the Memory Manager should use for the current zone. The grow-zone function should call the GZSaveHnd function to receive a handle to a relocatable block that the grow-zone function must not move
or purge.
