  bddindex   Index;
  bddnode   ∗High;
  bddnode   ∗Low;

BddSystem

The bdd system.

Index

The bdd index.

High

The bdd high pointer.

Low

The bdd low pointer.

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

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