3A critical section object is used for exactly the same purpose as 
4\helpref{mutexes}{wxmutex}. The only difference is that under Windows platform
5critical sections are only visible inside one process, while mutexes may be
6shared between processes, so using critical sections is slightly more
7efficient. The terminology is also slightly different: mutex may be locked (or
8acquired) and unlocked (or released) while critical section is entered and left
9by the program.

11Finally, you should try to use 
12\helpref{wxCriticalSectionLocker}{wxcriticalsectionlocker} class whenever
13possible instead of directly using wxCriticalSection for the same reasons 
14\helpref{wxMutexLocker}{wxmutexlocker} is preferrable to 
15\helpref{wxMutex}{wxmutex} - please see wxMutex for an example.

34\func{}{wxCriticalSection}{\void}

36Default constructor initializes critical section object.

44\membersection{wxCriticalSection::Enter}\label{wxcriticalsectionenter}
45
46\func{void }{Enter}{\void}
47
48Enter the critical section (same as locking a mutex). There is no error return
49for this function. After entering the critical section protecting some global
50data the thread running in critical section may safely use/modify it.
51
52\membersection{wxCriticalSection::Leave}\label{wxcriticalsectionleave}
53
54\func{void }{Leave}{\void}
55
56Leave the critical section allowing other threads use the global data protected
57by it. There is no error return for this function.
