GETBDDVARBYINDEX(3)

💖 GETBDDVARBYINDEX(3) 💖

okay bestie, welcome to the BDD FUNCTIONS corner of the man pages, where we're looking at getbddvarbyindex — the little glow-up that turns a bdd index into a variable number. it's giving translation-table realness and honestly? we're obsessed. 🦋

🌸 ORIGIN 🌸

so this software belongs to the ALLIANCE CAD SYSTEM, which was developed by the ASIM team at the LIP6 laboratory of Université Pierre et Marie CURIE, in Paris, France. 🇫🇷✨ iconic institution behaviour, no cap.

✨ SYNOPSIS ✨

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

---

🎀 PARAMETERS 🎀

• BddSystem — the bdd system, bestie. that's the whole vibe.
• Index — the bdd index we're about to convert. the main character of this function, fr fr.

---

💅 DESCRIPTION 💅

okay so here's the tea: getbddvarbyindex converts the bdd index Index to a variable number, inside the bdd system BddSystem. that's it. that's the job. 💖

and listen — if you hand it a null pointer, it just uses the default bdd system instead. no drama, no tears. 🙈

the way it does this is lowkey simple: it literally just uses the translation table BddSystem->INDEX_TO_VAR. that's the entire mechanism. periodt. ✨

---

👑 RETURN VALUE 👑

getbddvarbyindex returns the variable number of the bdd index Index. slay. that's the gift. 🎁

---

💀 ERRORS 💀

• "index xxx out of range, error !" — yeah so the Index parameter has to be a valid index. if it's not, you get this error. no skipping the vibe check on this one. 😭

---

🔥 EXAMPLE 🔥

here's a little demo, bestie, so you can see it in the wild:

#include "bdd101.h"
   bddsystem  ∗BddSystem;
   bddnode    ∗BddNode;
   BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
   BddNode = addbddvar( (bddsystem ∗)0, 0 );
   /* displays 0 */
   printf( "%d", getbddvarbyindex( (bddsystem ∗)0, BddNode->INDEX ) );
   destroybddsystem( (bddsystem ∗)0 );

and yes, the printf there displays 0. it said what it said. 💅

🫶 BUG REPORT 🫶

ngl, this tool is still under development at the ASIM department of the LIP6 laboratory. 🌱

we need your feedback to improve documentation and tools. fr fr, your girl is asking nicely. send the feedback. it's for the culture. 💜

and that's the whole page, bestie!! ✨ this one came from ASIM/LIP6, and it's dated October 1, 1997 — yeah, a vintage baddie, but she still runs. 💖🎀🦋 mwah, go forth and convert those indices. 👑
