NAME

6       addbddnode - adds a new bdd node in the bdd system.
7

SYNOPSIS

9       #include "bdd101.h"
10       bddnode ∗addbddnode( BddSystem, Index, High, Low  )
11         bddsystem ∗BddSystem;
12         bddindex   Index;
13         bddnode   ∗High;
14         bddnode   ∗Low;
15

PARAMETERS

17       BddSystem           The bdd system.
18
19       Index               The bdd index.
20
21       High                The bdd high pointer.
22
23       Low                 The bdd low pointer.
24

DESCRIPTION

26       addbddnode  adds a new node with the index Index, High as HIGH pointer,
27       and Low as LOW pointer in the bdd system BddSystem.  If  the  bdd  node
28       exist  already  addbddnode  return  its  pointer.  If a null pointer is
29       given, the default bdd system is used.
30

RETURN VALUE

32       addbddnode returns a pointer to the resulting bdd node with its  number
33       of external reference incremented.
34

ERRORS

36       "index xxx out of range"
37              The Index parameter must be a valid index.
