.SH PARAMETERS
.TP 20
\fIBddSystem\fP
The \fBbdd\fP system.
.TP
\fIOper\fP
The binary operator.
.TP
\fIBddNode1\fP
The first \fBbdd\fP node.
.TP
\fIBddNode2\fP
The second \fBbdd\fP node.
.SH DESCRIPTION
\fBapplybddnode\fP computes the boolean function \fIBddNode1\fP
\fIOper\fP \fIBddNode2\fP in the \fBbdd\fP system \fIBddSystem\fP.
If a null pointer is given, the default \fBbdd\fP system is used.
.br
.SH RETURN VALUE
\fBapplybddnode\fP returns a pointer to the resulting \fBbdd\fP node
with its number of external reference incremented.
.SH ERRORS
.if n \{\
.ft B \}
.if t \{\
.ft CR \}
"bad operator xxx error !"
.ft R
.RS
The \fIOper\fP parameter must be a valid binary operator.
