How can I use a linked list as a parameter for a function?

[Dennis]

Hello Everybody,

I have the problem, that I can not use a linked list as a parameter for a function?
What is the correct syntax/declaration for such a function??

Thx
Dennis

all linkedlists are declared in global.
so you can access them inside procedures.

something like that :

Code: Select all

NewList test.s()

Procedure AddItem()
  
  AddElement( test() )
  test() = "new item"
  
EndProcedure

AddItem()
Debug test()

AddElement returns a pointer to the linkedlist with containing the next and previous pointers.

Code: Select all

Structure something
  a.l
EndStructure

NewList abc.something()

AddElement(abc())  ; returns ptr to list of something
abc()  ; returns a ptr to something (I believe its offset of the ptr above)

[Dennis]

my idea was something like that:

Structure something
a.l
EndStructure

function add (localist.something())
addElement(locallist())
endFunction

newList myList.something

add(myList())


This way did not work!

I think you can only read the data from the ptrs, not treat them like a true PureBasic linkedlist.
