reserved until assigned to a \helpref{wxWindowIDRef}{windowidsoverview}
or unreserved with \helpref{UnreserveControlId}{wxidmanagerunreservecontrolid}.
Only ID values that are not assigned to a \helpref{wxWindowIDRef}{windowidsoverview}
need to be unreserved.

\wxheading{Parameters}

\docparam{count}{The number of sequential IDs to reserve.}

\wxheading{Return value}

The value of the first ID in the sequence, or \texttt{wxID\_NONE}.

\membersection{wxIdManager::UnreserveControlId}\label{wxidmanagerunreservecontrolid}

\func{static wxWindowID}{UnreserveControlId}{\param{wxWindowID}{ id}, \param{int}{ count = 1}}

Called directly by \helpref{wxWindow::UnreserveControlId}{wxwindowunreservecontrolid},
this function will unreserve an ID or range of IDs that is currently reserved.  This
should only be called for IDs returned by \helpref{ReserveControlId}{wxidmanagerreservecontrolid}
that have NOT been assigned to a \helpref{wxWindowIDRef}{windowidsoverview}

\wxheading{Parameters}

\docparam{id}{The first of the range of IDs to unreserve.}
