[Dev-C++] flexibla array

[<A_B...@gm...>]

Hi,
I'm trying to create an flexible array.
I have a structure named roomDat.
At the  1st und 2nd call of addRoom() every thing seems to be OK, but the =
second time the 
will no memory be reserved, because the ID is always 2 after the 1st call.=
..

[CODE]
extern roomDat* Raum;
int cSpiel::addRoom(){
  /* TODO (AB#1#): neuen Raum erstellen, ID zur=FCckgeben */
  int ID =3D 0;
  if(!Raum){
    Raum =3D (roomDat*)malloc(sizeof(roomDat)); 
    Raum->Prev =3D NULL;
    Raum->Next =3D NULL;
    Raum->ID =3D ++ID;
    sprintf(Raum->Name, lang[7], ID);
    Raum->Mesh =3D NULL;
    Raum->Node =3D NULL;    
    wnd_Anfang.addRoom(Raum->Name, Raum->ID);
  }else{
    roomDat* tmp =3D Raum;
    roomDat* tmp2 =3D NULL;
    while(tmp){
      if(tmp->ID > ID) ID =3D tmp->ID;
      tmp2 =3D tmp;
      tmp =3D tmp->Next;
    }
    tmp =3D (roomDat*)malloc(sizeof(roomDat)); 
    tmp->Prev =3D tmp2;
    tmp->Next =3D NULL;
    tmp->ID =3D ++ID;
    sprintf(tmp->Name, lang[7], ID);
    tmp->Mesh =3D NULL;
    tmp->Node =3D NULL;    
    wnd_Anfang.addRoom(tmp->Name, tmp->ID);
  }
  return ID;
}
[/CODE]

What's wrong ???
