Memory Management Routines

Managing Relocatable Blocks

The Memory Manager provides routines that allow you to purge and later reallocate space for relocatable blocks and control where in their heap zone relocatable blocks are located.

To free the memory taken up by a relocatable block without releasing the master pointer to the block for other uses, use the EmptyHandle procedure. To reallocate space for a handle that you have emptied or the Memory Manager has purged, use the ReallocateHandle procedure.

To ensure that a relocatable block that you plan to lock for short or long periods of time does not cause heap fragmentation, use the MoveHHi and the ReserveMem procedures, respectively.
