About the Moves Memory Icon

The following icon appears at the top of many of the pages describing traps.

This indicates that the trap may move or purge memory. You should be

careful to lock handles when using

traps, since any relocatable block

may move during the execution of that routine. See Handle for more

information. Traps that move or purge memory should not be called from

interrupt routines.

Warning: Apple has not completely documented the set of traps that may

move or purge memory. There are several traps (such as LNew

and OpenRF) that are known to move memory, although Apple

does not document them that way. There is an icon on all pages that

are known to move memory, whether Apple has documented this

fact or not. If a trap seems as though it is moving memory, it may

very well be, even if no "moves memory" icon appears on its page.

Apple reserves the right to reclassify any trap, so even traps that

are not marked with

might be in the future.
