NAME
unsetbddrefext - increments the internal reference, and decrements the external reference of a bdd node.man2html: unable to open or read file man1/alc_origin.1
SYNOPSYS
#include "bdd101.h" bddnode *unsetbddrefext( BddNode ) bddnode *BddNode;
PARAMETERS
- BddNode
- The bdd node.
DESCRIPTION
unsetbddrefext increments the number of internal reference of the bdd node BddNode and decrements its number of external reference.RETURN VALUE
unsetbddrefext returns the BddNode pointer.ERRORS
"negative reference, index xxx error !"- The BddNode must have a postive number of external reference.
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 ); incbddrefext( BddNode ); unsetbddrefext( BddNode ); /* displays Node VAR: 0 INDEX: 2 MARK: 0 REF_EXT: 0 REF_INT: 1 */ viewbddnode( (bddsystem *)0, BddNode ); /* displays (not i0) */ viewablexpr( Expr, ABL_VIEW_VHDL ); freeablexpr( Expr ); destroybddsystem( (bddsystem *)0 ); destroybddcircuit( (bddcircuit *)0 );
