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 sup- port 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 BddSystem->NUM- BER_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)
