increments the external reference of a bdd node.
SYNOPSYS
#include "bdd101.h"
bddnode *incbddrefext( BddNode )
bddnode *BddNode;
PARAMETERS
- BddNode
-
The bdd node.
DESCRIPTION
incbddrefext increments the number of external reference
of the bdd node BddNode.
RETURN VALUE
incbddrefext returns the BddNode pointer.
