.SH PARAMETERS
.TP 20
\fIBddSystem\fP
The \fBbdd\fP system.
.TP
\fIBddNode1\fP
The first \fBbdd\fP node.
.TP
\fIBddNode2\fP
The second \fBbdd\fP node.
.SH DESCRIPTION
\fBintersectbddnode\fP tests if the intersection of \fIBddNode1\fP and \fIBddNode2\fP
exists, in the \fBbdd\fP system \fIBddSystem\fP.
If a null pointer is given, the default \fBbdd\fP system is used.
.br
.SH RETURN VALUE
\fBintersectbddnode\fP returns the \fBbdd\fP node zero if there is no 
intersection, and a computed \fBbdd\fP node otherwise.
