.SH PARAMETERS
.TP 20
\fIBddSystem\fP
The \fBbdd\fP system.
.TP
\fIBddNode\fP
The \fBbdd\fP node to unmark.
.TP
\fIMark\fP
The bit mask.
.SH DESCRIPTION
\fBunmarkbddnode\fP unmarks the \fBbdd\fP node \fIBddNode\fP
with the bit mask \fIMark\fP, in the \fBbdd\fP system BddSystem.
If a null pointer is given, the default \fBbdd\fP system is used.
This function does a AND with the field MARK of the \fBbdd\fP node \fIBddNode\fP,
and the complemented bit mask \fIMark\fP.
.br
.SH RETURN VALUE
\fBunmarkbddnode\fP returns the number of the differents unmarked nodes.
