GETBDDVARNODEBYINDEX(3)

💅 GETBDDVARNODEBYINDEX(3) — bestie, let's talk bdd nodes

okay so this one lives in section 3 of the BDD FUNCTIONS manual, and it's genuinely one of the cutest little lookups in the whole bdd toolkit tbh 🎀

---

✨ NAME ✨

getbddvarnode — gives the bdd node of a variable. that's it, that's the whole job, and she does it flawlessly 💅

---

🌸 ORIGIN 🌸

bestie, this software belongs to the ALLIANCE CAD SYSTEM, developed by the ASIM team at LIP6 laboratory of Université Pierre et Marie CURIE, in Paris, France 🥖✨ iconic lineage fr fr

🦋 SYNOPSIS 🦋

#include "bdd101.h"
bddnode ∗getbddvarnodebyindex( BddSystem, Index )
  bddsystem ∗BddSystem;
  bddindex   Index;

---

🎀 PARAMETERS 🎀

• BddSystem — the bdd system. literally the system we're digging around in 🫶
• Index — the bdd index. the little number that points at your variable 👑

---

💖 DESCRIPTION 💖

okay so getbddvarnode gives you the bdd node of the bdd index Index, inside the bdd system BddSystem ✨

and here's the lowkey important part: if you hand it a null pointer, it just uses the default bdd system instead. no drama, no error, she's flexible like that 😌

and how does she do it? the function uses simply the table BddSystem->VAR_NODE — like, no cap, that's the whole trick, she just looks it up in the table 💅

---

🌈 RETURN VALUE 🌈

getbddvarnode returns a pointer to the variable bdd node 🫶 that's your node, bestie, go off

---

💀 ERRORS 💀

• "index xxx out of range, error !" — the Index parameter must be a valid index. like, it has to be valid, no exceptions, she will absolutely call you out 😭

---

⭐ EXAMPLE ⭐

#include "bdd101.h"
   bddsystem  ∗BddSystem;
   bddnode    ∗BddNode;
   BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
   addbddvar( (bddsystem ∗)0, 0 );
   BddNode = getbddvarnodebyindex( (bddsystem ∗)0, 2 );
   ...
   destroybddsystem( (bddsystem ∗)0 );

see how she sets up the system, adds a var, grabs the node at index 2, and then cleans up after herself with destroybddsystem? main character energy with manners 👑✨

🙈 BUG REPORT 🙈

this tool is under development at the ASIM department of the LIP6 laboratory 🛠️ and they need your feedback to improve documentation and tools — so like, please tell them things, they're literally asking 🫶

---

real talk: that error message "index xxx out of range, error !" fires when your Index isn't valid. keep your indices valid and we all stay happy 💜
