SYNOPSYS

 #include "bdd101.h"
 bddindex getbddvarindex( BddSystem, Variable )
   bddsystem *BddSystem;
   bddvar     Variable;
 

PARAMETERS

BddSystem

The bdd system.

Variable

The variable number to convert.

DESCRIPTION

getbddvarindex converts the variable number Variable to a bdd index, in the bdd system BddSystem. If a null pointer is given, the default bdd system is used. The function uses simply the translation table BddSystem->VAR_TO_INDEX.

RETURN VALUE

getbddvarindex returns the bdd index of Variable.

ERRORS

"variable xxx out of range, error !"

The Variable parameter must be less or equal to the BddSystem->NUMBER_VAR field.

EXAMPLE

 #include "bdd101.h"
    bddsystem  *BddSystem;
    bddnode    *BddNode;
    BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
    BddNode = addbddvar( (bddsystem *)0, 0 );
    /* displays 2 */
    printf( "%d", getbddvarindex( (bddsystem *)0, 0 ) );
    destroybddsystem( (bddsystem *)0 );
