delete an element from the list

Declaration

Source position: fgl.pp line 82

public 
  procedure Extract(Item: Pointer; ResultPtr: Pointer);

Description

Extract removes the item pointed to by Item from the list. It returns a pointer to the actually removed item from the list. The item is searched using TFPSList.IndexOf . If the item is not found, nil is returned.

Some descendents own the items in the list. Extract will not dispose of the item, as TFPSList.Delete does.

Errors

None.
