Just info about a few PB-Private-Vars (LLs)

[Lars]

Was it possible that the programmer gets access to the private PureBasic Vars which describes the current Linked List element, the first LL element and the last LL element (if they exist, but I think so )?
I need this, because I want to swap two LL elements by their pointers. If I swap the first element by Pointer, I get a problem, because PB gets a wrong element as the first/last.
Please help!

THX a lot!

It does, THX.
BUT: It would be nice to get access to the PB-FirstElement/PreviousEmelent-Vars anyway. The way above is not the
way i was looking for. Usualy it should be possible to swap two
LL-Elements by just swap their pointer. But THX a lot for your link.

PS: Another workaround: before swapping the pointer add one element at
the start and the end of the list and remove the elements after the
swapping. But this is not as fast as the way from the link.

The problem is you want to bash with the internal structure of PB objects which could be subjects to change in future release and invalidate all your code..

[Lars]

It is a pity. . .
Would it be possible then that you (fred) integrate a SwapLLElements()-Function in PB?

[Fred]

Sure, SwapElements() could be a nice addition. I will looking forward to a such function.

In Germany i would say "Wink mit den Zaunpfahl":

Edit: The routines only have problem with the first and last element and when the first parameter is after the second.

THX, that would be very nice.
