HeapLock Function (ROM Call 0x9A)

alloc.h

HANDLE HeapLock (HANDLE Handle);

Locks a block.

HeapLock locks the block referenced by Handle so that it is not moved during garbage collection. Returns Handle if OK, else returns H_NULL.

Note: Locking memory may cause the system to run out of usable memory sooner than if memory is kept unlocked.
