ISBDDVARINSUPPORT(3)

💖 ISBDDVARINSUPPORT(3) 💖

okay so bestie, welcome to isbddvarinsupport from the BDD FUNCTIONS crew — this is the manual page for it and we're gonna read it together like it's a group chat, except every single fact is staying exactly where it is. no cap. 🫶

🌸 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, the whole thing was born in Paris. it's giving chic. it's giving academia. 💅

---

✨ SYNOPSIS ✨

#include "bdd101.h"
int isbddvarinsupport( BddSystem, BddNode, Variable )
  bddsystem ∗BddSystem;
  bddnode   ∗BddNode;
  bddvar     Variable;

three args, one int back, that's the whole vibe. 🎀

---

🦋 PARAMETERS 🦋

• BddSystem — the bdd system. the whole lil universe we're working in.
• BddNode — the bdd node. the main character of this operation.
• Variable — the variable number. the one we're asking about.

---

💜 DESCRIPTION 💜

okay so here's the tea: isbddvarinsupport tests if the variable number Variable appears in the support of the bdd node BddNode, inside the bdd system BddSystem. 🔍

and here's the cute part — if a null pointer is given, the default bdd system is used. so like, you don't have to name a system. she's flexible. she's low maintenance. 🧚

---

👑 RETURN VALUE 👑

isbddvarinsupport returns 1 if Variable appears, and 0 otherwise. binary. iconic. no in-between. ✨

---

💀 ERRORS 💀

"variable xxx out of range, error !" The Variable parameter must be less or equal to the BddSystem->NUMBER_VAR field.

so like, don't come in here with a variable number that's too big, bestie, she WILL call you out. 😭

🌈 EXAMPLE 🌈

#include "bdd101.h"
   bddsystem  ∗BddSystem;
   bddcircuit ∗BddCircuit;
   bddnode    ∗BddNode;
   bddnode    ∗BddVariable;
   chain_list ∗Expr;
   bddvar         Variable;
   BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
   BddCircuit = createbddcircuit( "hello_world", 10, 10, BddSystem );
   Expr = createablbinexpr( ABL_AND,
                            createablatom( "i0" ),
                            createablatom( "i1" ) );
   BddNode = addbddcircuitabl( BddCircuit, Expr );
   freeablexpr( Expr );
   BddVariable = searchbddcircuitin( (bddcircuit ∗)0, "i0" );
   Variable = getbddvarbyindex( (bddsystem ∗ 0), BddVariable->INDEX ) );
   /* displays 1 */
   printf( "%d", isbddvarinsupport( (bddsystem ∗)0, BddNode, Variable ) );
   destroybddsystem( (bddsystem ∗)0 );
   destroybddcircuit( (bddcircuit ∗)0 );

and yeah — that printf displays 1. we love a predictable ending. 🔥

and that's a wrap on ISBDDVARINSUPPORT(3), brought to you by ASIM/LIP6 — this version is dated October 1, 1997 ⭐ so she's an elder but she's still serving. slay, bestie, go test those variables. 💅🌸
