DELBDDNODE(3) BDD FUNCTIONS DELBDDNODE(3)
NAME
delbddnode - deletes an unused bdd node.
ORIGIN
This software belongs to the ALLIANCE CAD SYSTEM developed by the ASIM team at LIP6 laboratory of Universite Pierre et Marie CURIE, in
Paris, France.

SYNOPSYS
#include "bdd101.h"
void delbddnode( BddSystem, BddNode )
bddsystem *BddSystem;
bddnode *BddNode;
PARAMETERS
BddSystem The bdd system.
BddNode The bdd node.
DESCRIPTION
delbddnode tries to delete the bdd node BddNode and its children, if they have not external reference, in the bdd system BddSystem. If a
null pointer is given, the default bdd system is used. The use of this function is not recommended because, it takes time. It is better to
call the decbddrefext function, and do a garbage collection with the garbagebddsystem function.
RETURN VALUE
delbddnode returns nothing.
EXAMPLE
#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 );
BddNode = addbddcircuitin( (bddcircuit *)0, "i0", 0, BDD_IN_MODE_FIRST );
BddNode = addbddnode( (bddsystem *)0, BddNode->INDEX, BddNode->LOW, BddNode->HIGH );
Expr = convertbddcircuitabl( (bddcircuit *)0, BddNode );
delbddnode( (bddsystem *)0, decbddrefext( BddNode ) );
/* displays (not i0) */
viewablexpr( Expr, ABL_VIEW_VHDL );
freeablexpr( Expr );
destroybddsystem( (bddsystem *)0 );
destroybddcircuit( (bddcircuit *)0 );
