HLock |
Function (ROM Call 0x99) |
Locks and dereferences a handle.
HLock locks a block referenced by Handle so that it will not
move on the next heap compression, and returns a pointer to the actual memory
block. Returns NULL in a case of error.
Note: Locking memory may cause the system to run out of usable memory
sooner than if memory is kept unlocked.
