+\membersection{wxCRIT\_SECT\_DECLARE}\label{wxcritsectdeclare}
+
+\func{}{wxCRIT\_SECT\_DECLARE}{\param{}{cs}}
+
+This macro declares a (static) critical section object named {\it cs} if
+{\tt wxUSE\_THREADS} is $1$ and does nothing if it is $0$.
+
+
+
+\membersection{wxCRIT\_SECT\_DECLARE\_MEMBER}\label{wxcritsectdeclaremember}
+
+\func{}{wxCRIT\_SECT\_DECLARE}{\param{}{cs}}
+
+This macro declares a critical section object named {\it cs} if
+{\tt wxUSE\_THREADS} is $1$ and does nothing if it is $0$. As it doesn't
+include the {\tt static} keyword (unlike
+\helpref{wxCRIT\_SECT\_DECLARE}{wxcritsectdeclare}), it can be used to declare
+a class or struct member which explains its name.
+
+
+
+\membersection{wxCRIT\_SECT\_LOCKER}\label{wxcritsectlocker}
+
+\func{}{wxCRIT\_SECT\_LOCKER}{\param{}{name}, \param{}{cs}}
+
+This macro creates a \helpref{critical section lock}{wxcriticalsectionlocker}
+object named {\it name} and associated with the critical section {\it cs} if
+{\tt wxUSE\_THREADS} is $1$ and does nothing if it is $0$.
+
+
+
+\membersection{wxCRITICAL\_SECTION}\label{wxcriticalsectionmacro}
+
+\func{}{wxCRITICAL\_SECTION}{\param{}{name}}
+
+This macro combines \helpref{wxCRIT\_SECT\_DECLARE}{wxcritsectdeclare} and
+\helpref{wxCRIT\_SECT\_LOCKER}{wxcritsectlocker}: it creates a static critical
+section object and also the lock object associated with it. Because of this, it
+can be only used inside a function, not at global scope. For example:
+
+\begin{verbatim}
+int IncCount()
+{
+ static int s_counter = 0;
+
+ wxCRITICAL_SECTION(counter);
+
+ return ++s_counter;
+}
+\end{verbatim}
+
+(note that we suppose that the function is called the first time from the main
+thread so that the critical section object is initialized correctly by the time
+other threads start calling it, if this is not the case this approach can
+{\bf not} be used and the critical section must be made a global instead).
+
+
+
+\membersection{wxENTER\_CRIT\_SECT}\label{wxentercritsect}
+
+\func{}{wxENTER\_CRIT\_SECT}{\param{wxCriticalSection\& }{cs}}
+
+This macro is equivalent to \helpref{cs.Enter()}{wxcriticalsectionenter} if
+{\tt wxUSE\_THREADS} is $1$ and does nothing if it is $0$.
+
+
+
+\membersection{::wxIsMainThread}\label{wxismainthread}
+
+\func{bool}{wxIsMainThread}{\void}
+
+Returns {\tt true} if this thread is the main one. Always returns {\tt true} if
+{\tt wxUSE\_THREADS} is $0$.
+
+
+
+\membersection{wxLEAVE\_CRIT\_SECT}\label{wxleavecritsect}
+
+\func{}{wxLEAVE\_CRIT\_SECT}{\param{wxCriticalSection\& }{cs}}
+
+This macro is equivalent to \helpref{cs.Leave()}{wxcriticalsectionleave} if
+{\tt wxUSE\_THREADS} is $1$ and does nothing if it is $0$.
