swapbddvar(3)
swaps two contiguous variables.
SYNOPSYS
#include "bdd101.h"
void swapbddvar( BddSystem, Variable )
bddsystem *BddSystem;
bddvar Variable;
PARAMETERS
- BddSystem
-
The bdd system.
- Variable
-
The variable to swap.
DESCRIPTION
swapbddvar swaps the variable number Variable with
the variable number Variable + 1, in the bdd system BddSystem.
If a null pointer is given, the default bdd system is used.
This function is usefull for the bdd nodes reordering.
RETURN VALUE
swapbddvar returns nothing.
ERRORS
"variable xxx out of range, error !"
-
The Variable and Variable + 1, must be valid variables number.
EXAMPLE
#include "bdd101.h"
bddsystem *BddSystem;
bddnode *BddNode1;
bddnode *BddNode2;
BddSystem = createbddsystem( 100, 1000, 100, 50000 );
BddNode1 = addbddvar( (bddsystem *)0, 0 );
BddNode2 = addbddvar( (bddsystem *)0, 0 );
swapbddvar( (bddsystem *)0, 0 );
destroybddsystem( (bddsystem *)0 );
