GETBDDNODESUPPORT(3) BDD FUNCTIONS GETBDDNODESUPPORT(3)
NAME
getbddnodesupport - gives the variable support of a bdd node.
ORIGIN

SYNOPSYS
#include "bdd101.h"
void *getbddnodesupport( BddSystem, BddNode, Mode )
bddsystem *BddSystem;
bddnode *BddNode;
int Mode;
PARAMETERS
BddSystem The bdd system.
BddNode The bdd node.
Mode The type of support.
DESCRIPTION
getbddnodesupport gives the support of the bdd node BddNode in the bdd system BddSystem. If a null pointer is given, the default bdd sys-
tem is used. If Mode is BDD_SUPPORT_CHAIN the support is returned using chain_list else it is returned using ptype_list. The support must
be freed using the freechain or freeptype functions.
RETURN VALUE
getablexprsupport returns a pointer to a chain_list or a ptype_list.
EXAMPLE
#include "bdd101.h"
bddsystem *BddSystem;
bddcircuit *BddCircuit;
bddnode *BddNode;
chain_list *Expr;
chain_list *Support;
chain_list *ScanSupport;
bddindex Index;
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 );
Support = getablbddnodesupport( (bddsystem *0), BddNode, BDD_SUPPORT_CHAIN );
for ( ScanSupport = Support;
ScanSupport != (chain_list *)0;
ScanSupport = ScanSupport->NEXT )
{
Index = (bddnode *)ScanSupport->INDEX;
printf( "%s ", BddCircuit->NAME_IN[ Index - BDD_INDEX_MIN ] );
}
freechain( Support );
destroybddsystem( (bddsystem *)0 );
destroybddcircuit( (bddcircuit *)0 );
