.SH PARAMETERS
.TP 20
\fIBddSystem
The \fBbdd\fP system.
.TP
\fIBddNode\fP
The \fBbdd\fP node.
.SH DESCRIPTION
\fBsatisfybddnode\fP finds a simple path throw the \fBbdd\fP \fIBddNode\fP
that reaches the constant \fBbdd\fP node one, in the \fBbdd\fP system \fIBddSystem\fP.
If a null pointer is given, the default \fBbdd\fP system is used.
.br
.SH RETURN VALUE
\fBsatisfybddnode\fP returns a \fBbdd\fP node that satisfies \fIBddNode\fP.
.SH ERRORS
.if n \{\
.ft B \}
.if t \{\
.ft CR \}
"index xxx out of range, error !"
.ft R
.RS
The \fIBddNode\fP parameter must be different from the \fBbdd\fP node zero.
