The storage heap is protected from accidental modification. When you call a Data Manager API that modifies the storage heap, it temporarily allows write access to the storage heap. That's what I was referring to. However, DmFindSortPosition doesn't modify the storage heap, or at least it shouldn't. (It's generally safe to assume that the comparison callback is non-destructive.) So I was wrong - there is no significant performance penalty for rolling your own binary search routine. -- Danny @ PalmSource -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
