ADDBDDNODELIST(3)

💅 ADDBDDNODELIST(3) — the addbddnodelist page

okay so this is addbddnodelist, straight out of the BDD FUNCTIONS manual, section 3, and honestly bestie it's giving "small function, huge glow-up" energy ✨

---

🌸 NAME 🌸

addbddnodelist — adds a node in a chain_list 💫

that's it, that's the whole gig. one node, one list, no cap.

---

🎀 ORIGIN 🎀

so this software belongs to the ALLIANCE CAD SYSTEM, developed by the ASIM team at the LIP6 laboratory of Université Pierre et Marie CURIE, in Paris, France 🗼🥖

• Web : http://asim.lip6.fr/recherche/alliance/
• E-mail : alliance-users@asim.lip6.fr

like, real ones built this. iconic behavior fr.

---

✨ SYNOPSIS ✨

#include "bdd101.h"
chain_list ∗addbddnodelist( BddSystem, HeadList, BddNode )
  bddsystem  ∗BddSystem;
  chain_list ∗HeadList;
  bddnode    ∗BddNode;

three args, one include, and you're in 💅

---

🦋 PARAMETERS 🦋

• BddSystem — the bdd system. yes. THE system. the one we're working in 🫶
• HeadList — the head of the chain_list. the leader of the pack, the main character of the chain 👑
• BddNode — the bdd node to add. this is the one getting inserted, slay 💖

---

💜 DESCRIPTION 💜

addbddnodelist adds the node BddNode in the ordered list HeadList, in the bdd system BddSystem 🌈

and here's the lil detail you cannot skip: if a null pointer is given, the default bdd system is used. so like, if you're lazy (affectionate) and pass (bddsystem ∗)0, the default one steps in for you. bestie energy honestly 🙈

also super important: the number of external reference of BddNode is incremented. so the node is being counted, and you should lowkey remember that, because refs are whole thing 👀

---

⭐ RETURN VALUE ⭐

addbddnodelist returns the new head of the list 💫

so like, catch it. don't just call it and ghost it, fr fr.

🔥 EXAMPLE 🔥

okay here's the whole thing, verbatim, no edits, because accuracy is the vibe:

#include "bdd101.h"
   bddsystem  ∗BddSystem;
   bddcircuit ∗BddCircuit;
   bddnode    ∗BddNode;
   chain_list ∗BddList;
   chain_list ∗Expr;
   BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
   BddCircuit = createbddcircuit( "hello_world", 10, 10, BddSystem );
   BddList    = (chain_list ∗)0;
   BddList = addbddnodelist( (bddsystem ∗)0, BddList,
                             addbddcircuitin( (bddcircuit ∗)0,
                                              "i0", 0, BDD_IN_MODE_FIRST ) );
   BddList = addbddnodelist( (bddsystem ∗)0, BddList,
                              addbddcircuitin( (bddcircuit ∗)0,
                                               "i1", 0, BDD_IN_MODE_FIRST );
   BddList = addbddnodelist( (bddsystem ∗)0, BddList,
                             addbddcircuitin( (bddcircuit ∗)0,
                                              "i2", 0, BDD_IN_MODE_FIRST ) );
   BddNode = applybddnodelist( (bddsystem ∗)0, ABL_AND, BddList );
   delbddnodelist( (bddsystem ∗)0, BddList );
   Expr = convertbddcircuitabl( (bddcircuit ∗)0, BddNode );
   /* displays (i0 and i1 and i2) */
   viewablexpr( Expr, ABL_VIEW_VHDL );
   freeablexpr( Expr );
   destroybddsystem( (bddsystem ∗)0 );
   destroybddcircuit( (bddsystem ∗)0 );

(wait — yes, that i1 line is exactly how it is in the original. i'm not touching it, i don't fix, i just vibe-check 💀)

and see that comment? /* displays (i0 and i1 and i2) */ — that's the payoff, that's the whole point of the example, we're ANDing three inputs together and viewing it as VHDL 🔥
