Memory Manager Routines

Freeing Memory

The Memory Manager compacts and purges the heap whenever necessary to satisfy requests for memory. You can also compact or purge the heap manually. To compact the current heap zone manually, use the CompactMem function. To purge it manually, use the PurgeMem procedure. To do both at once, use the MaxMem function. To perform the same operations on the system heap zone, use the CompactMemSys function, the PurgeMemSys procedure, and the MaxMemSys function.

Note

Most applications don't need to call the routines described in this section. Normally you should let the Memory Manager compact or purge your application heap.
