GETBDDVARNODEBYINDEX(3)

💖 GETBDDVARNODEBYINDEX — the manual page bestie 💖

okay so this is getbddvarnode from the bdd101.h world, and it's genuinely one of the cutest little functions ever — it just hands you the bdd node of a variable. that's it. that's the whole vibe. ✨

🌸 ORIGIN 🌸

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, they literally built a whole CAD system and we get to use it, no cap. 👑

✨ SYNOPSIS ✨

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

---

🎀 PARAMETERS 🎀

• BddSystem — the bdd system. the whole universe we're poking around in, basically. 🌌
• Index — the bdd index. the lil number that tells us which variable we want. 🔢

---

🦋 DESCRIPTION 🦋

okay so getbddvarnode gives you the bdd node of the bdd index Index, inside the bdd system BddSystem. it's giving "personal shopper but for graph nodes". 🛍️

and here's the tea: if you hand it a null pointer, it just uses the default bdd system instead. no stress, it's got you. 🫶

also, fun fact, this function does not do anything fancy or mysterious — it uses simply the table BddSystem->VAR_NODE. literally just a lookup. lowkey iconic for how unbothered it is. 💅

---

💜 RETURN VALUE 💜

getbddvarnode returns a pointer to the variable bdd node. that's your prize, bestie. 🏆

---

🔥 ERRORS 🔥

• "index xxx out of range, error !" — the Index parameter must be a valid index. so like… don't be out here passing nonsense, fr fr. 😭

---

🌈 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 it builds the system, adds a var, grabs the node, and then cleans up after itself like a responsible main character? we love to see it. 🌟

💀 BUG REPORT 💀

this tool is under development at the ASIM department of the LIP6 laboratory. they literally need your feedback to improve documentation and tools — so if something's weird, tell them, bestie. they're listening. 🙈
