.SH PARAMETERS
.TP 20
\fIBddSystem\fP
The \fBbdd\fP system.
.TP
\fIBddOff\fP
The first \fBbdd\fP node.
.TP
\fIBddDc\fP
The second \fBbdd\fP node.
.SH DESCRIPTION
\fBsimpbddnodedcoff\fP simplifies the \fBbdd\fP node \fIBddOff\fP with
\fIBddDc\fP, in the \fBbdd\fP system \fIBddSystem\fP.
If a null pointer is given, the default \fBbdd\fP system is used.
The \fBbdd\fP node \fIBddDc\fP must be included imperatively
in the off-set part of the \fBbdd\fP node \fIBddOff\fP.
.br
.SH RETURN VALUE
\fBsimpbddnodedcoff\fP returns the simplified \fBbdd\fP node.
