Re: [Vala] List problem in Valide

[gege2061 <gege2061 redaction-developpez com>]

I have found the problem: these functions directly compare the adress
of the keys.

Becareful, the find function return the node of the list, not the data !

void main ()
{
  SList<string> list = new SList<string> ();

  list.append ("one");
  list.append ("two");
  list.append ("three");
  list.append ("four");

  string key = "three";

  unowned SList<string> node = list.find_custom (key, strcmp);
  int ix = list.position (node);

  print ("%s - %d\n", node.data, ix);
}
