ISBDDVARINSUPPORT(3) BDD FUNCTIONS ISBDDVARINSUPPORT(3) NAME isbddvarinsupport - tests if a variable appears in a bdd. SYNOPSIS #include "bdd101.h" int isbddvarinsupport( BddSystem, BddNode, Variable ) bddsystem *BddSystem; bddnode *BddNode; bddvar Variable; PARAMETERS BddSystem The bdd system. BddNode The bdd node. Variable The variable number. DESCRIPTION isbddvarinsupport tests if the variable number Variable appears in the support of the bdd node BddNode, in the bdd system BddSystem. If a null pointer is given, the default bdd system is used. RETURN VALUE isbddvarinsupport returns 1 if Variable appears, 0 otherwise. ERRORS "variable xxx out of range, error !" The Variable parameter must be less or equal to the BddSys- tem->NUMBER_VAR field. EXAMPLE #include "bdd101.h" bddsystem *BddSystem; bddcircuit *BddCircuit; bddnode *BddNode; bddnode *BddVariable; chain_list *Expr; bddvar Variable; 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 ); BddVariable = searchbddcircuitin( (bddcircuit *)0, "i0" ); Variable = getbddvarbyindex( (bddsystem * 0), BddVariable->INDEX ) ); /* displays 1 */ printf( "%d", isbddvarinsupport( (bddsystem *)0, BddNode, Variable ) ); destroybddsystem( (bddsystem *)0 ); destroybddcircuit( (bddcircuit *)0 ); SEE ALSO bdd(1) ASIM/LIP6 October 1, 1997 ISBDDVARINSUPPORT(3)
