GETBDDNODENUM(3)

💅 GETBDDNODENUM(3) — BDD FUNCTIONS 💅

okay bestie, gather round, we're reading a 3 manpage (that's a library function, not a command, iykyk) from the BDD FUNCTIONS collection. it's giving vintage 1997 but the knowledge is timeless. 🦋

🌸 NAME 🌸

getbddnodenum — literally just gets the number of nodes in a bdd. that's it. that's the whole job. 💖

---

🌈 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 academic institution behaviour, no cap.

✨ SYNOPSIS ✨

#include "bdd101.h"
long getbddnodenum( BddSystem, BddNode )
  bddsystem ∗BddSystem;
  bddnode   ∗BddNode;

so you pull in bdd101.h, you hand it a BddSystem and a BddNode, and you get back a long. simple as that, fr fr. 🎀

---

🫶 PARAMETERS 🫶

• BddSystem — the bdd system. yes, the whole system. your main character.
• BddNode — the bdd node. the one we're counting around.

---

💜 DESCRIPTION 💜

getbddnodenum computes the number of different nodes in BddNode, in the bdd system BddSystem.

and here's the lil plot twist bestie: if you pass a null pointer, the default bdd system gets used instead. so you don't have to pick a system, the function will just pick the default one for you. the way that it's flexible?? obsessed. 😌

---

⭐ RETURN VALUE ⭐

getbddnodenum returns the number of the different nodes reached. that's your answer, that's your count, that's the whole tea. ☕

---

🔥 EXAMPLE 🔥

look at this absolute serve of a code sample:

#include "bdd101.h"
   bddsystem  ∗BddSystem;
   bddcircuit ∗BddCircuit;
   bddnode    ∗BddNode;
   chain_list ∗Expr;
   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 );
   printf( "Number nodes: %ld0,
           getbddnodenum( (bddsystem ∗)0, BddNode ) );
   destroybddsystem( (bddsystem ∗)0 );
   destroybddcircuit( (bddcircuit ∗)0 );

yes bestie, that printf line is exactly how it appears on the page — the %ld0, and the missing closing quote are quoted verbatim, i'm not touching a single character. 🫣✨ (also note the (bddsystem ∗)0 null pointers — that's the "use the default system" move in action, and then everything gets destroyed at the end like a responsible icon. 🧹)

💀 BUG REPORT 💀

this tool is under development at the ASIM department of the LIP6 laboratory.

they need your feedback to improve documentation and tools. so like, if something's wonky, tell them?? they're literally asking. your feedback is the moment. 🙈💌

and that's the page!! 💅

cute lil sign-off for the girlies who read all the way to the bottom: this page came from ASIM/LIP6 and it's dated October 1, 1997 — a whole era. it's a 3 page, it's GETBDDNODENUM, and it ate. periodt. 👑🌸🦋
